Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Thorlabs references — within one business day.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
