LAMBDA 850/950/1050 UV/Vis and UV/Vis/NIR …
UV/Vis/NIR RANGE Long the industry standard in spec-trophotometry, the LAMBDA 950 uses a gridless PMT with Peltier-controlled PbS detector to achieve high- performance testing across the spectral range up to 3300 nm. The UV/Vis resolution reaches 0.05 nm, while the NIR resolution reaches up to 0.20 nm.
