タイトルまたは説明

We are professional manufacturer of optical lenses and components such as Spherical Lenses, Prisms, Cylindrical Lenses, Windows, Filters etc.

We support customization from prototype to volume production and offer cost-effective solutions to pare down your budget. 

Longpass filters are ideal for a variety of applications, such as gas monitoring, temperature, sensing, thermal imaging and motion sensing, etc. Longpass filters block shorter wavelengths and transmit longer wavelengths. Blocking can be from reflectance, absorption or a combination. Transmission in the pass band can be enhanced with an antireflection coating on the second surface.
