86108H Spectrum Transmission Meter
Measure UV 365nm, IR 940nm, and Visible Light Transmittance (380–760nm) in One Test
Three Results in One Measurement
Parallel Light Path Design
1mm Test Aperture
The 86108H Spectrum Transmission Meter is a desktop instrument specifically designed to test the optical transmittance of various transparent materials, such as lenses, glass, coatings, plastics, and paints. With a 1mm test aperture, it is ideal for accurately measuring the transmittance of small-sized samples in the ultraviolet, infrared, and visible light ranges.
Its flat desktop design allows easy placement of different materials. Testing is quick and precise—results are displayed instantly upon placing a sample on the meter. Thanks to its parallel light path design, the device can also test materials with greater thickness without compromising accuracy.
The 86108H uses UV, IR, and visible light sources to illuminate the transparent sample. Sensors detect the intensity of incident light and the transmitted light through the sample. The transmittance is calculated as the ratio between transmitted and incident light, displayed as a percentage.
Application
Ideal for testing uniform transparent materials including glass, PC, coated glass, remote control IR windows, plastics, paints, lenses, acrylic, and other organic glass materials.

Features
Three-in-One Light Path Design
A single test aperture integrates three light sources—UV (365nm), IR (940nm), and visible light (380–760nm)—allowing all three measurements in one test. This simplifies operation and saves time.
Parallel Light Beam Design
The parallel light path ensures accurate and stable readings, even when testing thicker materials.
1mm Small Aperture
The 1mm aperture makes it suitable for evaluating the transmittance of small samples.
Real-Time Dynamic Self-Calibration
The meter features automatic real-time self-calibration, resetting to 100% transmittance each time it is powered on.
Stylish LCD Display
Equipped with a large LCD screen for easy viewing. Its sleek design makes it suitable for use at exhibitions or public demos.
5V Power Supply
Powered via a 5V connection, compatible with mobile power banks for convenient operation.

1. The difference between 86108H and 86183 spectrum transmission meter
Both 86183 and 86108H spectrum transmission meters can measure the transmittance of infrared, ultraviolet and visible light.
1) 86183 use a card slot design with a detector hole diameter of 10mm and width between the light source and the receiver is 47mm.
2) 86108H use a desktop design, the detector hole diameter is only 1mm and the height between the light source and the receiver is 20mm.
86108H is suitable for measuring small-sized materials and more widely used, so the price of 86183 is slightly higher. 86183 is suitable for measuring large-sized materials.
