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 customized services. And you need to pay additional customization fees.

  • The customized products do not enjoy the returns and exchanges policy, hope to get your understanding.
