Microscope Lenses
For the Model 320
The L37 lens is an optional accessory to the Model 320 which provides the capability to examine the thermal properties of very small objects. By itself, installed in place of the standard 25° or 50° lens, the L37 gives a field of view of just under a half-inch. When combined with the extender the resulting “L22” assembly has a field of view of slightly over a quarter-inch.
The L06 lens provides the ultimate in thermal magnification and has a field of view of less than a tenth of an inch. This means you can identify details as small as 6 microns.
