Welcome to the home of Firefly's solid-state UV-VIS Spectrophotometer Calibration Standards. 

This calibration plate includes the following well standards (covering 16 wells in total):

• HF-0.2 (60%T) 
• HF-0.5 (30%T) 
• HF-1.0 (10%T)    
• WAV-1 UV/VIS Solid State Holmium Oxide

Capabilities:

• Photometric accuracy in the VIS range (certified at 440, 465, 546.1, 590, 635nm).
• Wavelength accuracy in the UV and VIS range (241.5-637.5nm)

Product Specs:

• Tolerance for photometric accuracy filters: +/- 0.0022 au
• Tolerance for wavelength accuracy filters: +/- 0.2nm
• External dimensions of individual wells: 6.6mm per well
• Total dimensions for 96 well plate: 85x125x12.5mm

Benefits of Firefly's Solid-State Well Plate Calibration Standards:

• Highly accurate and consistent spectrophotometer calibration every time.
• Never has to be replaced.
• Never has to be recalibrated if handled and stored properly.
• Scratch-resistant coating protects optical surfaces.
• Can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45.0 mm holder)
• Surpasses NIST requirements and tolerances.
• NIST-traceable and ISO compliant.
