Shenzhen Speedre Technology Co. Ltd.

Description:

SDR851 lens transmittance tester is the use of ultraviolet light source, infrared light source and visible light source to irradiate the transparent substance under test, the sensor respectively detects the incident light intensity of the three light sources and the light intensity after passing the transparent substance under test, the ratio of the passing light intensity and the incident light intensity is the transmittance, expressed in percentage.

It is specialized in optical transmittance test of lens, glass, coating materials, organic materials, coatings and other light transmittance substances.

Parameters:

l Instrument dimensions: 200*180*106mm(L*W*H)

l Minimum test object size:￠1.0mm

l Instrument weight: 1500g

l Resolution: 0.1%

l Measurement accuracy:±1%

l Ultraviolet: center wavelength 365nm

l Visible light: 380nm-760nm full wavelength, center wavelength:550nm

l Infrared: Center wavelength 950nm

l Power supply: 9V AC/DC power supply

Instrument operation:

1: Plug in the power and turn on the power switch of the tester. The instrument first performs self-test and self-calibration. After the self-calibration is completed, the display values of the three displays are "100", indicating that the transmittance is 100% when there is no measured object.

2: Place the object to be tested in the test position. Three displays display the transmittance of the object to ultraviolet, infrared and visible light respectively.

Instrument characteristics:

1.Ultraviolet transmittance meter, infrared transmittance meter, visible light transmittance meter , 3 in 1.

2. Suitable for lens, paint, glass, mobile phone lens, organic materials and other transmittance test.

3. The instrument has a real-time dynamic self-calibration function and automatically calibrates to 100% transmittance after powering on.

4. The minimum test object size is ￠1.0mm.

5. Stainless steel desktop design, beautiful appearance, convenient for placing the measured object, and easy to operate.

Usage steps and precautions:

1. Connect the instrument to the dedicated power supply, keep the test position empty, and turn on the instrument switch;

2. Place the object under test into the test position;

3. Three display Windows display the transmittance of the object to ultraviolet infrared and visible light respectively;

4. When the instrument is not in use, please turn off the power;

5. The instrument performs self-test and self-calibration when it is turned on. The test position must be empty, otherwise the self-calibration cannot be completed;

6. Avoid contact with corrosive items and stay away from high temperature and high humidity environments;

7.Occasionally, when there is no test object, the displayed data cannot return to 100. Just shut down and restart the instrument immediately.

8. When used continuously for a long time, due to the luminous efficiency of the LED light source (the temperature of the LED light source increases, the efficiency decreases), the data in the three windows may not be displayed as 100. In this case, please turn off the power of the instrument and restart the self-test and self-test. Calibration does not affect measurement accuracy and normal use;
