FAQ

What does Vigitek do? +

Vigitek, Inc. designs and supplies optical, electro-optical, and laser-related products and subsystems, and also supports OEM and custom developments for biomedical and industrial applications.

What types of products do you offer? +

Our catalog includes engineering-grade components such as diode drivers, capacitor charging power supplies, controllers, and related electro-optical modules. Availability and configuration options vary by product.

Do you offer custom or OEM configurations? +

Yes. We support OEM and custom configurations for many products. Share your target specifications (electrical output, pulse parameters, interfaces, packaging, and any test/documentation needs), and we’ll recommend the best-fit option and quote accordingly.

Can you help me choose the right product? +

Yes. Send a short description of your application and key requirements (power, voltage/current range, pulse width and repetition rate, cooling constraints, interfaces, and intended use). We will help you select the most appropriate solution.

Do you provide documentation and test information? +

When applicable, we can provide user documentation and test information appropriate to the product and your requirements. If your program requires specific documentation or traceability, mention it when requesting a quote.

What support do you offer after purchase? +

We can assist with integration questions, configuration guidance, and troubleshooting. For the fastest support, include your order/invoice number and product model/serial number (if applicable), plus a clear description of operating conditions.

Do you ship within the United States? +

Yes. We ship within the U.S. using common parcel carriers (UPS/FedEx) and LTL freight for larger items when needed. Shipping options and costs are provided with your quote or order confirmation.

What are typical lead times? +

Lead times depend on the item and configuration. Standard items generally ship within the lead time shown on your quote. Custom or build-to-order items may require additional manufacturing and test time.

Why don’t you list prices on the website? +

Many Vigitek products are configured to match specific system requirements (electrical output, pulse parameters, interfaces, packaging, firmware, and test requirements). Publishing a single price can be misleading, so we provide quotes that match your exact application and quantity.

How fast can I get a quote? +

In most cases, we can provide a quote quickly once we have the key requirements (product/configuration, quantity, and ship-to location). For custom or highly specialized requests, we may ask a few technical questions to ensure accuracy.

What information should I send to get accurate pricing? +

Product name/part number (or a short description of what you need)
Key specifications (voltage/current range, pulse width/repetition rate, power, interfaces)
Quantity and expected order volume (prototype vs. production)
Desired lead time
Shipping destination (U.S.)

Do you offer discounts for volume or repeat orders? +

Yes. Pricing often improves with higher quantities and ongoing production. Let us know your forecast and we’ll quote the most appropriate tier.

Can you recommend a lower-cost alternative? +

Often, yes. If a standard configuration meets your needs (or if certain options aren’t necessary), we’ll suggest a simpler, more cost-effective approach.

Are custom/OEM projects priced differently? +

Custom and OEM developments are quoted based on scope, requirements, validation/testing, and deliverables. We’ll outline what’s included so you can compare options clearly.

How do warranty and returns work? +

Warranty and return eligibility vary by product and are confirmed on your quote or order confirmation. Returns generally require prior authorization. If you believe an item is defective or damaged in transit, contact us promptly with details and photos.

Return Policy

Vigitek, Inc. aims to ensure you receive products that meet specifications and perform as intended. Because many items are technical, configured, or built to order, returns are handled through a Return Authorization (RA) process.

Return Authorization (Required)

Please contact us to request an RA before returning any item. Returns sent without prior authorization may be refused.

Email: sales@vigitek.biz
Phone: +1 (203) 829-5756

Eligibility

Defective or damaged items: If you believe an item is defective or was damaged in transit, contact us promptly with your order/invoice number and photos (and video if helpful). We may request troubleshooting information and/or return for evaluation.
Non-defective returns: If approved, non-defective returns must typically be unused, unmodified, and in original packaging, and may be subject to a restocking fee. Shipping charges are non-refundable unless required by law or agreed in writing.
Custom/OEM items: Custom, configured, or build-to-order items are generally non-returnable except for warranty/defect evaluation, unless otherwise stated in writing.

Return Window

If a non-defective return is approved, the return window and shipping address will be provided with the RA. Items received outside the approved window may be refused.

Packaging and Shipping

Pack items carefully to prevent damage in transit. Transit damage caused by inadequate packaging is not covered.
Include the RA information as instructed and any documentation requested (e.g., issue description, operating conditions).
Unless otherwise stated in writing, the customer is responsible for return shipping costs.

Evaluation and Outcomes

After inspection/testing, we will determine the appropriate outcome based on the issue and the terms of your purchase, which may include repair, replacement, credit, or refund (as applicable). If no fault is found or the issue is outside warranty/return eligibility, evaluation fees and return shipping may apply.

Questions

If you are unsure whether an item qualifies for return, contact us before shipping anything back.

Warranty Policy

Vigitek, Inc. provides a limited warranty on select products we manufacture and sell (for example: diode drivers, capacitor charging power supplies, and controllers). Warranty coverage and duration may vary by product and will be confirmed on your quote, order confirmation, or invoice. For custom/OEM developments or engineering services, warranty terms are governed by the applicable project agreement.

Warranty Coverage

This limited warranty covers defects in materials and workmanship under normal use and service, when the product is installed, operated, and maintained according to Vigitek documentation or written instructions. Warranty coverage begins on the date of shipment or delivery (unless otherwise stated in writing).

Not Covered

Normal wear and tear, cosmetic damage, or consumable parts (if applicable).
Damage caused by misuse, abuse, accidents, improper handling/storage, improper installation, or operation outside published specifications.
Damage caused by electrical issues (incorrect voltage, wiring errors, power surges), environmental conditions beyond the product rating, or inadequate cooling/ventilation.
Failures resulting from unauthorized modifications, firmware changes, tampering, or repair/service performed by anyone not authorized by Vigitek.
Integration issues with third-party components or systems, unless explicitly included in the written scope for a supplied system.
Downtime, lost profits, or other indirect/incidental/consequential damages (to the extent permitted by law).
Labor for removal/reinstallation, on-site service, and shipping/freight unless explicitly stated in writing.

How To Request Warranty Service

Repair the product/part, or
Replace the product/part with the same or a functionally equivalent item (new or refurbished), or
Provide a refund/credit up to the purchase price of the affected item/part.

Repaired or replaced items are covered for the remainder of the original warranty period, unless otherwise required by law.

Returns and Packaging

Products returned for evaluation must be packaged appropriately to prevent transit damage and must display the RA information as instructed. Items returned without prior authorization may be refused. Transit damage is not covered by this warranty.

Pricing

Why We Don’t Publish Prices Online

Many of our products are engineering-grade components (drivers, power supplies, controllers, and electro-optical modules) that are often configured to match a customer’s exact system requirements. Because specs, compliance needs, test requirements, and quantities can vary significantly, a single “list price” rarely reflects the best or most accurate cost for your application.

Pricing Depends On Your Requirements

Configuration: Output power, voltage/current range, pulse parameters, interfaces, packaging, and firmware options can change cost.
Compliance & documentation: Medical/industrial requirements, traceability, and test documentation may affect scope and lead time.
Quantity: Volume and repeat orders often qualify for better pricing.
Lead time: Standard vs. expedited builds can change cost and availability.

What You Get Instead

Fast, accurate quotes: We respond with pricing that matches your exact needs.
Right-fit recommendations: If there’s a simpler or more cost-effective option, we’ll suggest it.
Clear lead times: Quotes include realistic build and ship timing.
