Naming Scheme - identify the right objective for your application!


LT is short for "Low Temperature (compatible)”.

APO is short for "Apochromatic", and refers to the fact that the focal displacement curve is flat (i.e. within plus/minus one depth of focus) within the specified apochromatic range (see specification sheets of the respective objectives for further details).

/VISIR is short for "Visible to (near-)infrared", indicating that the objective is most suitable for the visible to (near-infrared) wavelength range.

/0.82 is indicating the numerical aperture (NA) of the respective objective, in this case NA = 0.82.
