How to select a suitable Light Transmission Meter?

Linshang light transmission meters are widely used to measure various transparent materials, such as glass, PC, PET, PMMA, acrylic, etc. You can choose the appropriate spectrum transmission meter according to the table below.

I. The Classical Applications of Light Transmission Meters

Model	Test Slot Width/Height	Test Hole Diameter	Classical Application
LS108A Lens transmission meter	20mm	1mm	IR ink hole, IR-cut filter, IR remote control filter
LS108D Lens transmission meter	20mm	0.5mm	IR ink hole, IR-cut filter, IR remote control filter
LS108 Lens transmission meter	20mm	1mm	Sunglasses and all kinds of anti-blue materials
LS108H Light transmission meter	20mm	1mm	Especially for small sized, irregular shaped materials
LS182 Light transmission meter	47mm	10mm	Only for regular, flat materials with larger size
LS183 Light transmission meter	47mm	10mm	Only for regular, flat materials with larger size

II. The Light Sources of Light Transmission Meters

Model	Visible / Blue Light	UV / Purple Light	Infared Ray
LS108A	550nm	/	850nm / 940nm
LS108D	550nm	/	850nm / 940nm
LS108	380-760nm / 430nm	395nm (UV400)	/
LS108H	380-760nm	365nm	940nm
LS182	380-760nm	365nm	940nm / 1400nm / Full IR
LS183	380-760nm	365nm	940nm

III. Frequently Asked Questions

1. What is the difference between the LS183 and LS108H spectrum transmission meters?

The LS183 spectrum transmission meter uses a slot design, and LS108H uses a desktop design, the material placement for the LS108H is more convenient than LS183 spectrum transmission meter.
The LS183 spectrum transmission meter is made of aluminum shell material, LS108H is made of stainless steel, which is more durable.
The LS183 spectrum transmission meter is more suitable for measuring regular, flat materials with larger size, such as glass, PC plate. The LS108H can not also measure the above materials, but also suitable for small sized, irregular shaped materials.

2. What's the "UV400" measured by LS108 lens transmission meter?

"UV 400" means that the lenses will block 100% Ultraviolet (UV) waves shorter than or equal to 400nm
For example: "UV400=371nm" means the total UV blocking effect of the test object can only reach 371nm.

3. Can I customize the light source with different peak wavelength？

Linshang light transmission meter has certain requirements on the built-in light source, not all light sources are compatible. If we can purchase the light source of the specific wavelength you need on the market, we can provide you with customization services. And you need to pay additional customization fees.
The customized products do not apply to the returns and exchanges policy. Thanks for your understanding.
