Cylindrical Lens, +80mm f.l., Unmounted
$45.00This is a plano-cylindrical lens. These lenses have a defined magnification in one direction, and perpendicular to that direction they are effectively ‘unpowered’. Cylindrical lenses find numerous applications in holography, as well as imaging elongated slits in spectrometers and monochromators.
Characteristics of this lens include:
� Focal length – Positive 80mm
� Length – 60mm
� Width – 30mm
� Manufacturer – Melles Griot
� Part number – 01-LCP-009
� Glass type – BK7
� Uncoated
� Low precision figure
� Condition – no visible defectsPlease note – unless we are able to determine that a lens is a higher precision type (either by part number or by nomenclature on the lens itself) then it should be assumed that the lens has a low precision figure. When we have determined that a lens is definitely a low precision grade, then that will be stated in the lens characteristics.

Anamorphic Laser Beam Prism Pair 2.2x Mounted
$199.00Special Optics 18-2009 Anamorphic Laser Beam Prism Pair, 2.2x, Mounted.
used excellent condition.This device is used to selectively amplify an image (or beam) in one direction while leaving the orthogonal direction unchanged. A typical application is that of laser diodes in which the output beam cross-section is elliptical instead of circular. By suitable arrangement of a pair of triangular prism wedges, various anamorphic magnification ratios can be established.
One consequence of this modulation is that the output beam, while parallel to the input beam, is offset relative to the input beam in the direction of the modulation. Special Optics have housed these prism pairs in sturdy black anodized aluminum cells. The input and output faces are threaded with the proper amount of offset relative to each other.
� Anamorphic magnification – 2.2x
� Beam offset – ~5mm
� Antireflection coating 860nm
� Part number – 18-2009
� Thread inside diameter – 1.08 inches
� Base dimensions – 2.25 inches wide, 2.11 inches long
� Centerline height, including base – approximately 1 inchThese prisms housings do show very light signs of previous use, but the glass appears to be without flaws. Please note that photo of 820nm coating prism system was recorded twice – we have several of both types.

Microscope with 10x Crossline 32mm
$300.00This microscope is very modular. The central component is the drawtube with focusing mechanism. The body of the instrument is fitted with a long 1 inch diameter threaded flange which is supplied with a locking ring. The thread allows the microscope to be attached to various Gaertner instruments, such as the precisions cross slides, instrument bases with cross-support arms, among others. The rack and pinions focusing has a range of 38mm. The nominal optical tube length of the microscope is 160mm.
Eyepieces are supplied with matched eyepiece adapter tubes so the optical tube length is maintained when switching eyepieces. The tube adapters are usually fitted with spider cross lines and therefore no attempt should be made to clean them! These microscopes are all fitted with the standard M250-242 adapter tube with 90 degree spider lines. The ocular is a type M242 Ramsden 10x, also standard.
Gaertner objectives are continuously threaded over their entire length (RMS standard thread) and have a locking ring. The continuous thread allows precise adjustment of the magnification ratio of the instrument when using micrometer eyepieces or filar eyepieces. Focal length of the objectives supplied with these instruments is 32mm (Gaertner part number M220).
As outfitted, the instrument has the following characteristics:
� 40x total magnification.
� 38mm working distance
� 2.75mm diameter object fieldAn optional component, the image erecting eyepiece adapter, may be installed instead of the eyepiece adapter tube. Depending on the adapter chosen, the eyepiece angle can be either 60 degrees or 90 degrees from the microscope axis, and an erect image is obtained due to the use of a special roof prism. Due to the extended optical tube length of the prism, the above characteristics would be slightly altered. We have these adapters listed elsewhere.
These microscopes are in good condition. They are in excellent mechanical and optical condition. Cosmetically, they show some evidence of use and may have minor alterations that do not affect typical function of the instrument (such as the addition of a tapped hole in the body tube).
