LS117

Optical density meter

Introduction

The light source of the LS117 densitometer adopts the principle of diffuse transmission measurement. It is an advanced translucent material light transmittance meter with the effect of an integrating sphere. The light source conforms to the CIE photopic function standard, which can ensure that it passes the inspection of the Institute of Metrology. The instrument is suitable for the light transmittance and optical density test of milky white diffusion plate, zirconia, aluminized film, X-ray film, foggy, frosted glass and other materials.

Relevant optical knowledge science: Optical density is optical density, abbreviated as OD, which means the light-shielding ability of materials. It is commonly referred to as absorbance, and the national standard is called optical density. It refers to the logarithm of the ratio of incident light to transmitted light or the logarithm of the reciprocal of light transmittance. The calculation formula is: OD=lg (incident light/transmitted light) or OD=lg (1/light transmittance).

Features of LS117 light transmittance test instrument

1. High precision and wide measurement range, the optical density value can be measured to 6 OD.

2. The light transmittance and optical density can be tested at the same time, and directly displayed on the screen.

3. The light source of the optical density meter adopts the principle of diffuse transmission, which meets the test requirements of milky white and foggy materials. And the light source conforms to the CIE photopic function standard, ensuring that it passes the national measurement.

4. The optical density meter is equipped with a fixed base and a bracket. There are two measurement methods: either the fixed base can be used for testing, or the probe can be taken down to test larger-sized materials.

FAQ

QDoes this one have a battery?

A Yes, a regular AA battery.

QWhat is the difference between the light transmitance tested by the LS117 Optical Density Meter and the integrating sphere principle instrument?

A Diffuse transmissive materials can be measured by the milky glass method and the integrating sphere method. Our LS117 uses the milky glass method. The milky glass method has slightly larger light transmitance data than the integrating sphere method, and the reverse light Density value is slightly smaller. But these two are test methods recognized by national standards, and LS117 ensures that it can pass the national Measurement.

QLS117 test mobile phone cover screen printing inks OD value data jumps a lot?

A Because the light transmitter of silk screen inks is already very low, the light transmitter is already at the level of one ten thousandth, and the mobile phone panel has a certain thickness, the subtle changes in external light will have an impact, especially the milky white silk screen inks, which need to be tested in the dark room.

QWhat is the difference between the diffuse transmission principle LS117 and the haze meter?

A The measurements are two completely different parameters and are not comparable. 1. Haze meter measurement is the percentage of the transmitted light intensity above the 2.5 ° angle of deviation from the incident ray to the total transmitted Light intensity. The greater the haze, the worse the Glossiness, transparency and imagery of the measured material. 2. The LS117 measurement of the principle of diffuse transmission is the percentage of the total light intensity transmitted to the original Light intensity, which is the total light transmitter of the measured material. The larger the light transmitter, the better the light transmission performance of the measured material.

QWhy does LS117 use flannel when testing high-permeability materials?

A Because the rays of light will reflect each other between the milky white Glass and the sample at the receiver end, the light transmitter value will be too large. For materials with actual transmittance values greater than 96%, the test value may show 100%. When testing very high transparency materials, it is recommended to apply flannel to reduce the reflection area at the receiver end.
