Firefly's FUV neutral density solid-state filter series tests photometric accuracy in the UV and VIS range from 200-700nm. Our solid-state nano-deposition technology produces unparalleled stability and means that you will never need to recalibrate this filter.

• Economic - no recalibration fees and replacement filters
• Save time by having standards in your lab where they are needed
• Save on having to handle fragile and toxic liquid calibration standards
• Give yourself peace-of-mind knowing that all our standards are 100% NIST Traceable
• High durability with scratch-resistant coating that protects optical surfaces

Capabilities: Photometric accuracy in the UV and VIS range
Stray light performance in the UV and VIS range (with matching HF Series filter)
These standards will work on any spectrophotometer.

Standard peaks included on certificate of calibration are 250, 280, 340, 360, 400, 465, 500, 546.1, 590 and 635nm.
