High Performance Short Pass Filter

What is a short pass filter?

A shortpass filter is an optical filter that allows short-wavelength light to pass through. While it blocks longer-wavelength light.

The cutoff point of this filter is typically defined by the wavelength at which the transmittance is 50%.

And light with a wavelength lower than the cutoff wavelength has a high transmittance, while light with a wavelength higher than the cutoff wavelength is strongly suppressed.

The  features of the short pass filter:

• High transmission: The transmission rate in the target short-wave region can reach over 90%.
• Sharp Cut-off: Can precisely distinguish the transmission zone from the cutoff zone.
• Stable Performance: Utilizing the medium coating technology, it features the ability to withstand high power and environmental changes.

Applications of short pass filters:

The filters has various types of features. Therefore, it has various typs of applications:

• Astronomy

• Spectroscopy & Research

• Fluorescence Microscopy

• Laser and Optical Systems

• Industrial & Imaging Systems

Chengyu short pass filter exhibits outstanding blocking performance within the suppression band, while maximizing the transmission rate within the passband.

High-performance short-pass filters can be combined with our long-pass filters to create custom precision band-pass filters.

Also, we support customization and provide more types of short pass filters. If you deed it, please consult with our staff.
