Bandpass filter
A type of optical filter that transmits any specific wavelengths and blocks out other unnecessary light.
It is possible to set any central wavelength (transmission wavelength) from the ultraviolet to infrared range, and create a custom setting for the half-width, stop band, etc.
It has been used for analytical equipment, medical equipment, sensors, exposure machines, etc.
Infrared Bandpass Filters
Near-infrared to far-infrared bandpass filters are optical components that are widely used in optical communications,
industrial equipment, medical equipment, gas concentration sensors, etc.
We receive many requests for wavelengths such as 1550nm, 1064nm, 2.75㎛, 3.3㎛, 4.25㎛, and 4.75㎛.
We have an infrared spectrophotometer to evaluate down to 20μm.
This product is also useful in the security field, with heat detection, infrared sensors, and gas detection capabilities.
Examples of applications: gas sensors, YAG lasers, optical isolators, optical communication base station equipment, optical sensors, etc.
Specific examples include its use in optical fiber for communication, gas detectors, and fire alarms.
It is also used to detect heat, including human body temperature.
This technology is also indispensable for investigating global warming phenomena.’

UV High Durability Bandpass Filter
This is a bandpass filter that transmits ultraviolet light and absorbs visible light.
It is mainly used to extract only ultraviolet light.
Our ability to process thin films that are resistant to ultraviolet rays, which affect deterioration over time, has earned us praise from customers.
We can handle orders for just one piece, so we can also accommodate requests for use in research and development, etc.
