LS117 Densitometer Introduction: The LS117 Densitometer is an optical instrument made with the diffuse transmission principle. It is suitable for optical density test of aluminized film, film, X-ray film, lens ink and other materials. It is also an advanced light transmittance meter with integral sphere effect. It is suitable for light transmission of milky white translucent material and frosted matte material. Rate test. Such as pattern or frosted glass, ceiling lamp cover and other materials. The instrument light source complies with the CIE Ming visual function standard, ensuring detection by the metrology institute. Optical Knowledge: Optical density (OD) is defined as the characterization of the material's ability to block light. The optical density has no dimension unit and is a logarithmic value. The optical density is the logarithm of the ratio of the incident light to the transmitted light or the logarithm of the reciprocal of the transmittance. The calculation formula is OD=log10 (incident light/transmitted light) or OD=log10 (1/light transmittance). Features: 1. Adopt diffuse transmission optical path design to meet the testing requirements of fog materials. The light source complies with the CIE Ming visual function standard and ensures detection by the metrology institute. 2. With the fixing seat and bracket, you can fix the test, or you can take the probe and test the larger size material. 3. Simultaneous measurement of optical density, relative optical density, dot area ratio and light transmittance. 4. It is suitable for light transmittance test of various materials such as frosted glass, zirconia, aluminized film and milk white diffuser. Technical Parameters: Light source: 380nm-760nm full wavelength, in line with CIE Ming visual function standard Optical density resolution: 0.01 OD Optical density measurement accuracy: ±0.02 (0 --- 2.00 OD) / ±2% (2.00 --- 6.00 OD) Optical density measurement range: 0.00 OD --- 6.00 OD Light transmittance resolution: 0.0005% Transmittance measurement accuracy: ±1% (0% --- 50%) / ±2% (50% --- 100%) Dot area measurement range: 0 --- 100% Light hole size: 2mm Instrument dimensions: length 130mm * width 70mm * height 28mm Instrument weight: about 500 grams (without battery) Power supply: 4*AAA alkaline dry battery
