Wavelength accuracy is determined by scanning a wavelength filter with sharp, clearly defined transmission peaks and comparing the results to those on the certificate of calibration provided

• Scratch-resistant coating protects optical surfaces
• Patented nano-deposition manufacturing process means that filters never have to be recalibrated if used properly
• Wavelength accuracy in the UV and VIS range (329 – 875 nm)
• Photometric accuracy in the UV range (270 – 340 nm)

Its highly accurate and consistent spectrophotometer calibration every time. It can be used in any spectrophotometer (with standard 12.5 x 12.5 x 45 mm holder).
