720–1100nm Acrylic IR Pass Filter

The720–1100nm Acrylic IR Pass Filteris an infrared optical filter designed to transmit 

near-infrared wavelengths while reducing visible light transmission.

With a nominal passband of720nm to 1100nm, the filter is suitable for optical 

systems that need to isolate infrared wavelengths from visible light.

The filter is manufactured fromacrylic optical materialand features a lightweight 

1mm-thick construction, making it suitable for compact optical assemblies and electronic devices.

720nm Long Pass Optical Filter

This filter can be used as a720nm long pass filter, allowing wavelengths above approximately 

720nm to pass through while suppressing shorter visible wavelengths.

The 720nm cutoff region makes the filter suitable for applications where visible light 

needs to be reduced and near-infrared signals need to be detected.

The nominal transmission range is:

720–1100nm

Multiple Standard Sizes

Three standard circular sizes are currently available:

• Ø6.5 × 1mm
• Ø11 × 1mm
• Ø24 × 1mm

The compact circular design allows the filter to be integrated into different optical housings, 

camera assemblies and sensor systems.

Custom dimensions can also be supplied according to customer requirements.

Lightweight Acrylic Optical Material

Compared with conventional optical glass filters, acrylic provides a lightweight material option for optical and electronic products.

The acrylic filter is suitable for applications wherelow weight, compact dimensions and infrared wavelength filteringare important.

Applications

Infrared Imaging

The 720–1100nm passband can be used to reduce visible light and allow near-infrared wavelengths to reach an imaging sensor.
