Protective FiltersFilters

Lens Protection-LP Series

Protective Filters are designed to shield your lens and lighting from dirt, dust, liquids, impact and harsh environments without sacrificing image quality.


LP Series - Lens Protection

Protective Filters are useful in all imaging applications. The LP285 can withstand high temperatures and is impact resistant (similar qualities to Pyrex). LP170 fused silica protective windows are made from an ultra-pure, synthetic optical material similar to fused quartz. They offer extremely low thermal expansion, high-resistance to shock, superior scratch resistance and excellent optical properties. They perform well in high-temperature applications, having the ability to withstand temperatures of up to 1100° C. They are also chemical resistant and have superior transmission in the UV through near infrared spectral ranges.
