The FM31-LWD fits in the palm of your hand…. Compact, portable, reasonably priced. These were manufactured in Japan by Swift Optical.

Ideal for large animal vet work, avian specialists and mobile vets. Don't let the size of this instrument fool you. It can do just about anything that a Lab scope can do, except for 1000x. However, with optional 15x and 20x eyepieces and the 40x LWD objective, yields up to 800x magnification.

Applications: Urine, Blood, Semen (pc), Parasites, etc. in field.

All models are equipped with a 10x widefield eyepiece with a 15.5mm FOV (field of view), 4x, LWD 10x, and LWD 40x objectives.

Depending on available stock some microscope comes complete with a handy carrying case.

Optional Mechanical stage and a phase annulus may be available. Please inquire.

PLEASE NOTE: The microscopes pictured are a representation of our selection and may not be the exact one ordered, however in most cases they will be the microscope pictured. If not, they will be as identical as possible.
