Dichroic Mirror, DM Fluorescence Dichroic Mirror DM565

Dimensional Tolerance: ±0.5 mm Surface Quality: 80-50 or higher Surface Figure: 4~6λ or better

Neutral-density filters make photographic exposure easy to control. By blocking light from reaching the camera sensor, they allow the camera to maintain a larger aperture for longer.

Coating: Antireflection coating Surface Quality: 40/20 Guaranteed peak transmission: >90%

A bandpass filter passes frequencies within a specified range and rejects or attenuates frequencies outside it, selectively transmitting part of the spectrum while rejecting all other wavelengths.

Filter Type [LP Series]: Optical interference or colored-glass filter

Long-pass filters serve gas monitoring, temperature sensing, other sensing, thermal imaging, and motion detection. They block shorter wavelengths and transmit longer wavelengths. Blocking can result from reflection, absorption, or both. An antireflection coating on the second surface can improve passband transmission.

Material: BK7 Glass， Fused Silica or Color glass Dimension Tolerance: +0.0/-0.2 Thickness Tolerance [General]: ±0.2 mm

Multilayer-coated filters are made from materials such as Bk7, fused quartz, colored glass, and sapphire. Baijing Optoelectronics supplies bandpass, dichroic, short-pass, and long-pass multilayer-coated filters.

Material: Color glass Dimension Tolerance: +0.0/-0.2 Thickness Tolerance [General]: ±0.2 mm

Colored-glass filters are widely used in displays, CCDs, microscopy, photometry, radiometry, imaging, astronomy, instrumentation, and aerospace. Schott, Hoya, and domestic colored glasses are available for ultraviolet, visible, and near-infrared wavelengths.
