Ultraviolet (UV) lamps emit light in the 200–400 nm wavelength range (see Chapter 2 for more details on the nature of UV light). About 56% of these are ultraviolet lamps, 3% are water treatment, and 1% are uv lamp. Aspheric condenser lenses (available uncoated for 380 - 2100 nm or with an AR coating for 350 - 700 nm or 650 - 1050 nm) are ideal for collimating the light from our unmounted LEDs with a center wavelength from 405 nm to 1600 nm. TUV T8 lamps are double-ended UV-C (germicidal) lamps used in professional air disinfection units. 5 x 8 W 254 nm or 365 nm. Often called germicidal or ozone absorption lamps, they are very stable light sources. The 254 nm shortwave UV models can be used for biochemical testing, mercury detectors, optical alignment, DNA analysis, electrophoresis, and more. Wavelength: 254nm. Special low-pressure mercury vapor lamps produce ultraviolet radiation at 254 nm, the optimal wavelength for disinfection and ozone destruction. The lamp also has a bright LED torch at the end – so you can see your way in the dark and inspect minerals in brighter light. Features Short-wave UV-C radiation with a peak at 253. Get it as soon as. (Qi Wei) ZF-1 three UV analyzer with UV lamp / desktop 254/365nm A,ZF-1Table three UV analyzer features ZF-1Table three UV analyzer is one of our company 's ultraviolet instrument products can emit long wave ultraviolet365nmHigh intensity, good stability, easy to use, reliable, welcomed by the majority of users. CAMAG UV Lamp for short-wave UV light 254 nm: The lamp housing is made of anodized aluminum and of shock-resistant plastic. The average UV fluences of 19. The light has a light bluish glow. The significance of 222 nm is that it does not cause molecular disruption to organic tissue, unlike conventional 254 nm UV disinfection lamps. Germicidal UV Replacement Bulbs, 254 nm UV Replacement Bulbs, Quality UV Replacement Bulbs. This ensures instantaneous ignition of the selected tube and the absence of any "flickering". Lamp, HX 5P 60″ 254nm VALIDATED. We have been engaged in the special lighting of UV&IR lamps since 1999. Lutron UVC-254SD UVC Ultra Violet Light Meter includes a Real time Datalogger High precision UVC measurement with Built-in Time/Date Stamp and real time data recorder (sampling time can be set at intervals of 1 second to 3600 seconds) and stored on optional SD memory card.
