700nm Long Pass Filter for IR Imaging and Machine Vision

700nm Long Pass Filter for IR Imaging and Machine Vision

Our 700–1100nm Long Pass Infrared Optical Filter is designed for

optical systems that require near-infrared transmission while blocking shorter visible wavelengths.

Designed for Near-Infrared Applications

With a nominal 700nm cut-on wavelength,

this long pass filter can be used to separate near-infrared wavelengths from shorter visible wavelengths.

Typical applications include:

· IR imaging

· Machine vision

· Optical sensing

· Infrared inspection

· NIR optical systems

· Measurement equipment

· Customized optical instruments

Multiple Substrate Options

The filter can be manufactured usingBK7, optical glass or

fused silica substrates to meet different optical system requirements.

Dielectric Multilayer Coating

A multilayer dielectric coating is used to provide

the specified transmission and blocking performance.

Single-side and double-side coating configurations are available.

Standard and Custom Sizes

Available standard diameters include10mm, 15mm,

20mm and 23mm, with different thickness configurations.

Custom diameter, thickness and optical specifications

can also be supplied for OEM projects.

Custom Infrared Optical Filters

We support customized longpass optical filters

based on customer drawings and application requirements.

Customers can specify the required:

· Cut-on wavelength

· Passband

· Blocking range

· Optical density

· Diameter

· Thickness

· Substrate

· Coating

· Surface quality

· Flatness

For custom requirements, send us your wavelength range,
