XENON-SAPPHIRE 3.9/95MM 25-1071819 16K Macro High Resolution Line Scan Lens

The Schneider Optics Xenon-Sapphire 3.9/95 (p/n: 25-1071819) is a 95mm focal length macro lens. This high-resolution, high-speed lens is optimized for the use with 16k pixel line scan sensors. The Xenon-Sapphire 3.9/95 is broadband coated and can be used in the range of 400 – 1000 nm. The V-mount makes it easy to install and rotate into the desired azimuth position for a wide range of high resolution applications.

The Xenon-Sapphire 3.9/95 provides three significant stop positions that are especially marked on the stop ring:

• F#3.9 is the maximum opening of the stop and provides maximum brightness. The mechanical vignetting at this F/number is only approx. 10% at the edge of the field. The MTF for 100 lp/mm is very high up to the edge of a 58 mm field. Due to the high aperture the lens is more sensitive with respect to change of magnification.
• F#4.8 shows maximum MTF and practically diffraction limited performance over the whole field. The depth of field is bigger but the lens is still sensitive to magnification changes. At 4.8 the lens is basically free of artificial vignetting.
• F#5.7 produces more diffraction which reduces the MTF slightly but is now extremely homogenous over the entire field. The lens shows this performance for the complete magnification range from -0.26 < ß < -0.21 and performs well for a magnification range of -0.28 < ß < -0.20 at a 16k performance of 100 lp/mm.
