NIST SRM 930e compliant kit for photometric accuracy in the VIS range (400-700nm)

Firefly Scientific's equivalent of the NIST SRM 930e calibration reference kit for verification of photometric accuracy in the VIS range.

Delivery includes:

• FF-HF-0.5 calibration standard 0.5AU (30% transmission)
• FF-HF-0.7 calibration standard 0.7AU (20% transmission)
• FF-HF-1.0 calibration standard 1.0AU (10% transmission)
• FF-A30 holder
• FF-CASE-P4 case

Specifications:

• Tolerances of the photometric accuracy filters: FF-HF-0.5 +/- 0.0022AU, FF-HF-0.7 +/- 0.0023AU, FF-HF-1.0 +/- 0.0023AU
• Wavelength range: 400-700nm 
• External dimensions of the indiviudal filters: 12.5 x 12.5 x 45.0mm

Advantages of Firefly Scientific's solid state calibration standards:

• 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-930e requirements and tolerances
• NIST compliant
