Module Introduction
1. Low Temperature Objective
Objective Datasheet:
• Numerical aperture NA = 0.84
• Corrected for use without cover glass and infinite tube length
• Focal length ca. 3.1 mm
• Magnification about 60x
• Free aperture on the side of the parallel light Ø 6,15 mm
• A/R coated for the visible (400 to 1100 nm)
• Correction achromatic for 450 to 1100 nm
• Useable down to 420 nm, with absorption down to 400 nm
• Calculated wavefront quality Lambda/10 to Lambda/20 pv in the center
• Lambda/5 in object fields up to Ø 30 µm
• Mechanical free working distance min. 0.4 mm (from holder)
• Free working distance ca. 0.8 mm (from last lens vertex)
• Holder made from titanium alloy
• Metal surfaces (Titanium) without anodizations
• Lens barrel provided with slits parallel to the optical axis to allow for
different thermal expansions of lenses and lens barrel and to allow for
degassing and replacement of gas between the lenses(all cavities within
the entire objective open to the exterior)
