XENON-SAPPHIRE 4.5/95MM 25-1068013 16K Macro Line Scan Lens

The Schneider Optics Xenon-Sapphire 4.5/95 25-1068013 is a high resolution 95mm focal length 16K line scan lens. The high resolution of the Xenon-Sapphire 4.5/95 lenses make full use of the sensor's pixel size of 3.5 µm and fully exploits all possibilities of the latest sensor generation. They are compact, robust and lockable in distance and apertures.

The 400 to 1,000 nm broadband coating makes the Xenon-Sapphire 4.5/95 suitable for applications in the visible and the near infrared spectrum. The V-mount makes it easy to install and rotate into the desired azimuth position for a wide range of high resolution applications where existing 12k lenses (with approximately 5 µm pixel sizes) are not sufficient anymore.

The XENON Sapphire 4.5/95 provides three significant stop positions that are especially marked on the stop ring:

F#4.5 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#5.4 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 5.4 the lens is free of artificial vignetting. F#6.4 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 -0.12 < ß’ < -0.05 and performs well for a magnification range of -0.17 < ß’ < -0.03 at a 16k performance of 100 lp/mm.
