High Sensitive Si-Photodiode for UV detection

We developed a new Si-Photodiode (HPV-1KB), which has a much  improved sensitivity to blue and ultraviolet region, and has a suppressed sensitivity in the infrared region,compared with conventional products by our unique process technology.It uses a glass cap made from quartz which prevents imparing light sensitivity.You can use it in a light signal input unit of apparatus required high detection accuracy against the wavelength from a ultraviolet to visible region.
