ML2500 Halogen Trinocular Brightfield Biological Microscope

The Meiji Techno ML2500 Trinocular Brightfield Biological Laboratory Series is one of our most rugged fully equipped microscope systems from Japan with a Flat-top Mechanical Stage and forward facing nosepiece. It offers many high performance features and a stable rectangular base for stability. High resolution DIN Standard SM Plan objectives offer crisp, clear, high contrast images and are offered as part of the standard package. A built in integrated Koehler illuminator with a field iris and 6V 30W Halogen lamp and variable intensity control is provided standard equipment to complement the SM PLAN optics. A green monitor lamp is lit to indicate that the lamp is on for easy on/off recognition in any laboratory setting. The low voltage, high intensity, pre-centered halogen lamp provides high level illumination can be adjusted to maximize the evenness of the bulb illumination and is readily accessible for a quick bulb replacement. The ML2500 Series also features a specially designed Achromatic N.A. 1.25 condenser with iris diaphragm and filter carrier. The die cast metal stand has a chemical resistant finish and is the most rugged, durable finish in the market today. Equipped with low position factory calibrated coaxial coarse and fine focus controls, tension adjustment and a built in stage stop lever to protect the specimen and objectives from accidental damage during use. The ML2500 Series Laboratory Biological Microscope is a versatile and modular system designed to accept a wide variety of optional accessories and is backed by Meiji Techno’s Limited Lifetime Warranty.
