It is constructed from black anodized aluminum and features a precision dovetail mounting rail for integration into optical bench systems, spectrometers, monochromators, and other scientific instruments.
Applications:
- Spectroscopy
- Monochromators
- Optical bench experiments
- Laser optics
- Diffraction studies
- Scientific instrumentation
Condition:
- Slit appears straight and intact
- Moderate cosmetic scratches from laboratory use
- D.W. Mann engraving remains sharp and legible
- Dovetail mount appears undamaged
- Internal slit assembly appears complete
Suggested eBay Title:
D.W. Mann Co. 20µ Precision Optical Slit Aperture Spectrometer Laboratory Optics
Suggested Buy It Now Price:
$249.99 OBO
Notes:
The 20-micron slit is substantially finer than many general-purpose laboratory apertures and would be of interest to spectroscopy enthusiasts, optical bench builders, telescope instrument makers, and collectors of vintage scientific equipment.
