Yes, you can. Please call our office and ask to speak with a chemist or email chemistry@vernier.com with your required wavelength and contact information.

Custom LEDs will have longer wait times and special pricing. We will contact you once we know we can make the LED, how long it will take, and its pricing. Please leave plenty of time for these requests.

Make sure we don’t already offer the LED you are requesting: https://www.vernier.com/product/fluorescence-led-cartridges/
