NIST 2031b compliant kit for photometric accuracy and stray light performance in the UV/VIS range (2

Firefly Scientific's equivalent of the NIST SRM 2031 calibration reference kit.

Capabilities:

• Validation of photometric accuracy in the UV/VIS range (200-700nm) 
• Validation of stray light performance in the UV/VIS range (200-700nm)
• NOTE: FF-FUV-0.04 is not suitable for stray light performance!

Delivery includes:

• FF-FUV-0.04 calibration standard 0.04AU (90% transmission)
• FF-FUV-0.5 calibration standard 0.5AU (30% transmission)
• FF-FUV-1.0 calibration standard 1.0AU (10% transmission)
• FF-A30 holder
• FF-CASE-P4 case
• Calibration certificate

Specifications:

• Tolerance of the photometric accuracy filters: FF-FUV-0.04 +/- 0.0019AU, FF-FUV-0.5 +/- 0.0039AU, FF-FUV-1.0 +/- 0.0042AU
• Wavelength range: 200-700nm. Standard peaks in calibration certificate: 250, 280, 340, 360, 400, 465, 500, 546.1, 635nm 
• External dimensions of the individual filters: 12.5 x 12.5 x 45.0mm

Advantages of Firefly Scientific's FUV photometric accuracy filters:

• Highly accurate and reproducible calibration of your spectrophotometer
• Never has to be replaced
• Never needs recalibrating if handled and stored correctly
• Scratch-resistant coating protects optical surfaces
• Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45.0mm holder)
• Fulfils or surpasses NIST-2031b requirements and tolerances
• NIST traceable
