This product is a specialized laser barrier masterbatch specially developed for the field of laser protection, suitable for laser protection lenses with multiple band barriers.

Especially considering the laser protection wavelength range of around 200-450nm and 750-1500nm. There are various options for light transmittance, including high transmittance of 70% and low transmittance of 30%. If the OD value is above OD4, choose the appropriate product based on the required light transmittance of the customer’s board.

The amount of addition is determined by the thickness of the board, and the thicker the board, the smaller the required amount of addition. Similarly, the thinner the material, the higher the amount added. If the customer needs a higher OD value, they need to increase the amount added.

The following is the spectrum of the high transparency product:

This product is made of inorganic materials and has excellent weather resistance. Sample testing is available.
