Features:

Standard transmittance calibration filter

Absorbance calibration filter

Standard neutral density attenuator

Standard absorption attenuator

Use: used for absorbance and transmittance calibration, such as spectrophotometer calibration, transmittance tester calibration, spectrum analyzer calibration, etc.

Using wavelength: 610nm

Attenuator type: The filter is made of doped optical glass. After designing and adjusting the thickness and doping, it is made into a standard transmittance attenuator to ensure a certain transmittance value. It is a non-coated absorption attenuator.

Standard transmittance type:

Transmittance: 92.64%±5%; thickness: 2mm
