Diodes Quadrant SiC (UV)

Les détecteurs à 4-Quadrants JQA5 de IFW consistent en un arrangement de 4 éléments de Carbure de Silicium, de 1 x 1 m², séparés de 0.2 mm. Chaque quadrant couvre la plage spectrale 205 -355 nm.

The active material is silicon carbide, which makes the diode "solar blind". The total diameter of the active area is 2.525 mm, and the surface area of each single quadrant is 1.25 mm². The distance between the quadrants is 32 µm, which, compared to the discontinued previous model (i.e., the JQC4) has been reduced by a factor of 5.

The typical sensitivity is 0.14 A/W in the important spectral range around the 254 nm line of mercury steam lamps and around the 248 nm line of the excimer laser. The "R” in the article number refers to the polarity, which has been inversed compared to the previous model. The JQC5R is now available.
