Raman Filter is an optical filter used in Raman spectroscopy. We have recentry developed long pass edge filters for Raman spectroscopy. These filter have high transmittance and hign OD. We offer these filters in one piece. Please contact us if you are interested! For product specification, please see raman filters page.

Automatic Wavelength Variable Filter We developed new filter module. It is easy to carry out the control in connection with a PC. If you have any interest in this device, please contact us.
Fiber Output Multi-wavelength Laser Source This laser source compatible with various wavelengths. Select any 1 to 3 wavelengths and output from a single fibre. If you have any interest in this device, please contact us.
Visible Light Wavelength Tunable Filter with Exchangeable Filter (VTFM/FC) Wavelength of our conventional TFM/FC is 1260～1650nm. This new VTFM/FC can be used in 480-850 nm. Wavelength range of main unit(VTFM): 80 nm (CWL ±40 nm) Tunable range of filter cassette (FC): 10nm If you have any interest in this device, please contact us.
SWIR filter (Broadband filter) Short wavelength infrared (SWIR) light is generally defined as light in the 900-1700 nm wavelength range. SWIR filter is known to be used for foreign object and semiconductor inspection. Our products can be used as a wavelength selective filter for products with infrared image sensors (IMX990/IMX991). If you have any interest in this filter, please contact us.
We’ve updated a page of Long Pass Filter. We have developed Long pass filter with wide and flat blocking lange. Wavelength can be selected as you wish. If you have any interest in this, please contact me.
