Visible light transmittance and optical density can be measured simultaneously Measuring accurately, and ensure it can pass the inspection of Chinese national relevant metrology institute
LS117 densitometer is an instrument that can measure both optical density and light transmittance. The instrument adopt the diffuse transmission principle which is suitable for the optical density test of opalescent translucent materials and frosted matte materials. The light source of the instrument complies with the CIE photopic luminosity function and can pass the inspection of Chinese national metrological institute.
Application
Suitable for testing optical density of aluminized film, film, X-ray film, lens ink and other materials. The optical density meter is suitable for testing the light transmittance of opalescent translucent materials, matte materials.
Features
High resolution, wide optical density measurement range
The optical density meter has wide measuring range. The optical density value can be measured to OD 6. The transmittance resolution is up to 0.005%
Light transmittance and optical density are measured simultaneously
During the test, the interface displays both the transmittance value and the optical density value of the material
Diffuse transmission light path design
The LS117 portable densitometer uses a diffuse transmission light path design, which has the same effect of the integrating sphere. There are relevant instructions in "GB / T 11500-2008 / ISO 5-2: 2001". The regulation has stated that “Use opale glass method instead of integrating sphere method as the basis of ISO standard diffuse transmission density"
High-precision and great accuracy
The light source complies with the CIE photopic luminosity function to ensure that it passes the testing of the Chinese Metrology Institute
Two measurement ways for more flexible to use
The optical density meter has two measurement methods which is more flexible to use. Fixed measurement: It is more suitable for testing regular or smaller objects. Hand-held measurement: take the probe down for testing, which is more suitable for irregular and large-volume materials
Pedestal measurement
Field measurement
Qualifications and Standards
