Advantages of acrylic lens cover
Light transmittance: the light transmittance of PMMA is very high, respectively.
Glossy light: PMMA is the most excellent polymer transparent material at present, with a light transmittance of 92%, which is higher than that of glass.
Ultraviolet light: quartz can completely pass through the ultraviolet line, but the glass is so expensive that ordinary glass can only pass through 0.6% ultraviolet light, but PMMA can pass through 73%.On the other hand, under UV irradiation, PMMA has better stability than polycarbonate.
Outlines: PMMA allows outlines that are less than 2800nm wavelengths to pass.When the IR, of longer wavelengths is smaller than 25000nm, it can basically be blocked. There is a special colored PMMA, that allows a specific wavelength IR to pass through and block the light at the same time.
