Infrared Block & Visible Pass Filters

The BP550 filter is designed for colour imaging applications where ultraviolet and infrared wavelengths must be blocked while maintaining accurate visible colour rendition.

This filter effectively passes visible light without discolouring the image while also serving as a protective dust cover.

The hard-coated low-expansion glass construction provides excellent thermal stability and durability in demanding lighting environments.

Extended infrared rejection out to approximately 1550nm provides improved heat removal compared with standard hot mirror filters.

SP645 filters block much of the red and near infrared spectrum, making them ideal for CCD and CMOS sensor integration.

The steep transition point and excellent infrared rejection provide superior colour balance and imaging performance.

These filters are also useful for suppressing the glow from hot metals, glass and other high temperature materials.

SP675 filters block portions of the deep red and infrared spectrum while maintaining strong visible light transmission.

The steep cut-off point and excellent IR rejection performance make this filter well suited for colour camera sensor integration.

SP700 filters provide broad visible light transmission together with strong infrared blocking performance.

This extended hot mirror filter continues infrared rejection out to approximately 1550nm.

The low-expansion Borofloat substrate and anti-reflection coatings improve transmission while reducing glare.

SP700 filters are commonly used in monochrome imaging systems and heat rejection applications.

SP730 filters provide excellent colour rendition by preserving the full visible spectrum while blocking infrared wavelengths.

These crystal-clear hot mirror filters are designed for colour cameras without integrated IR blocking filters.

The hard-coated low-expansion substrate provides excellent heat resistance and long-term stability.

SP730 filters are also suitable for suppressing the glow from hot metals, glass and high-temperature materials.
