Visible light transmittance and reflectance tester

Visible light transmittance and reflectance tester

This device is used to measure the visible light transmittance and reflectance of products such as car windows and plastic films.

The HA-TR model is a device for measuring reflectivity and transmittance, while the HA-T model only measures transmittance.

Applicable fields:

This instrument uses tungsten halogen lamps, parallel light tubes, integrating spheres, photocells, etc. to test the ratio of light flux before and after passing through glass. By using a specially designed filter, the ultraviolet and infrared components of the tungsten halogen lamp spectrum are filtered out to obtain the relative radiation spectrum of the A light source. This tester can be used for the visible light transmittance and reflectance of all transparent and semi transparent parallel flat objects such as flat glass, coated glass, laminated glass, tempered glass insulated glass, etc
