Densitometer LS117 Optical Density Meter Test Translucent Aluminum X-ray Film with OD Visible Light Transmittace Overview LS117 Optical Density Meter (2nd) Linshang 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 aluminized film, film, X-ray film, lens ink and other materials. The light transmittance test of opalescent translucent materials and frosted matte materials, such as zirconia, opalescent acrylic and so on. The light source of the instrument complies with the CIE photopic luminosity function and can pass the inspection of Chinese national metrological institute. Features 1. 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%. 2. During the test, the interface displays both the transmittance value and the optical density value of the material. 3& 65294; 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". 4& 65294;The light source complies with the CIE photopic luminosity function to ensure that it passes the testing of the Chinese Metrology Institute. 5. The optical density meter has two measurement methods which is more flexible to use.
