Neutral gray glass ZAB4 is a neutral density filter with the following core characteristics and applications:(Neutral Desity Glass,Industrial Testing Optical Filter,Production of neutral gray glass,Neutral gray glass OEM)
1. Basic characteristics
Neutral transmittance: uniformly attenuates light within the visible light range of 400-700nm without altering color balance.
Transmittance: Model "ZAB4" indicates an average transmittance of approximately 0.4% (specific values need to be adjusted according to thickness).
Material: silicate or borate glass, with high optical flatness and mechanical strength.
2. Technical parameters
Thickness effect: Increasing thickness will reduce light transmittance, which needs to be customized according to requirements.
Temperature resistance: Ordinary models have a temperature resistance of ≤ 100 ℃, and high-temperature environments require tempering treatment (≤ 200 ℃).
3. Application scenarios
Photography and videography: used to control exposure ti…
