This component features a package weight of 1.70 lbs per unit and was initially released on January 27, 2012. Currently, lifecycle status requires verification against current manufacturer documentation, and inventory is available in stock overseas. Submit the exact part number, quantity, and application requirements for a quote.
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.
For a faster response, include quantity, condition, and delivery destination.
