Neutral Colored Glass Filters are named based on the average transmissivity characteristics in 400nm to 700nm wavelength with 2mm thick For example ZAB70 means 70%.
Neutral Colored Glass Filters
Product review:
Neutral Colored Glass Filters, also known as Neutral Density (ND) filters, are optical components that uniformly reduce light intensity without significantly altering spectral composition.
Neutral Colored Glass Filters are named based on the average transmissivity characteristics in 400nm to 700nm wavelength with 2mm thick.
Sample is 70%, then it's named as ZAB70. And there are ten types of glasses in this part. But three types of them(ZAB65,ZAB30,ZAB5)are tested in 440nm-660nm wavelength.
Scope of Use:
1. Photography & Videography;
2. Optical Measurement & Laboratory Research;
3. Industrial & Machine Vision;
4. Display & Lighting Testing;
5. Astronomical Observation.
