An optional 0.5X supplementary lens (P/N 18750) changes the magnification range from 3.25X to 22.5X and increases the working distance to 6".

Microscope is available mounted on either a single arm boom stand, dual arm ball-bearing boom stand, or articulating arm that clamps onto surfaces up to 2.5" thick. The articulating arm preserves precious work surface area by giving the user limitless flexibility to position the microscope anywhere within a 32" radius from the vertical column. Light sources are optional accessories and must be purchased separately.
