They are short-wavelength absorbing and UV transmitting filters with the transmission limit wavelength within the ultraviolet region, which are intended to absorb light shorter than the set wavelength and transmit light longer than it.
It is possible to mold into aspherical lens and lensarray.
- *Patent information
- JP5100741 "ULTRAVIOLET SHIELDING GLASS"
- JP5904864 "ULTRAVIOLET-VISIBLE REGION TRANSMITTING GLASS"
Application
UV sterilization, analysis equipment, etc.
UV sharp cut filter ＜ITY series＞Compared to interference filters, this glass filter has a steep slope from the visible light. In addition, it is less affected by the angle of incidence and absorbs ultraviolet rays effectively.
It is used to protect the panel of LCD projectors and to reduce chromatic aberration when taking pictures with a camera.
- *Patent information
- US7951733, JP5142139 "BLUE-VIOLET LIGHT BLOCKING GLASS"
- US7951733 "BLUE-VIOLET LIGHT BLOCKING GLASS"
Application
LCD projector panel protection, camera filter
UV transmitting, Visible absorbing filter ＜IUV series＞With the rapid development of information-based society, the application of light has expanded beyond the optical industry into other industries. For instance, because of their higher energy level, ultraviolet rays are becoming more widely used.
Our IUV series is a bandpass filter with a transmittance peak in the ultraviolet region. It is used to absorb light in the visible range and extract only specific wavelengths in the UV range.
Application
UV illuminance meter, UV sensor
