650nm IR blocking filter Cut Optical Low-Pass Filter, Custom For CCTV Security Cameras

 

Felix Glass 650nm IR cut optical low-pass filter is a dedicated optical component for CCTV security surveillance cameras. This low-pass filter transmits visible light within 400–650nm and fully suppresses infrared radiation above 650nm, while functioning as an optical low-pass element to reduce moiré interference and false color distortion in imaging.

 

We adopt standard N-BK7 optical glass as substrate with precision interference blocking coating, delivering stable spectral performance to ensure true color reproduction for day-night security camera monitoring.

 

 

- Cut-off Wavelength: 650nm

We provide full one-stop processing: glass cutting, precision shaping, IR blocking coating, edge finishing, spectral transmission testing and surface visual inspection.

Prototype sampling, small trial batches and mass production are supported. Every optical low-pass filter is inspected to meet customer-specified spectral and dimensional requirements before delivery.

 

 

Please provide your required size, shape and spectral tolerance. Our optical engineering team offers customized 650nm IR cut OLPF solutions and factory competitive quotation.

 

 

It transmits 400–650nm visible light and blocks all infrared light over 650nm; meanwhile, the low-pass structure reduces moiré aliasing and eliminates false color in CCTV camera images.

Standard N-BK7 optical glass is used as substrate, paired with professional infrared blocking coating for stable day-night imaging performance.

Yes, we support custom round and square outlines, adjustable thickness, edge blackening and special spectral blocking parameters per technical drawings.

It is widely applied to all types of CCTV security cameras, home surveillance modules and vehicle-mounted monitoring optical systems.

We offer prototype sampling, small batch orders and large-scale manufacturing, all filters pass full spectral and dimensional inspection before shipment.
