As a clinician, lab supervisor or medical tech, you need a better biological microscopes that fit your needs and job demands, BM36U Series infinite microscopes adopt infinite optical system, which are ideal for clinical, university and institutional applications. It can be expanded for applications of phase contrast, fluorescent observations by selecting corresponding accessories.
Features (Compact, lightweight body, and easy to use)
1. Infinite-corrected Optical System
An infinity-corrected optical system basically has the following advantages because a parallel light beam passes between the objective lens and tube lens.
A magnification does not change even if the distance between the objective lens and tube lens is changed. Even if a parallel flat plate is inserted between the objective lens and tube lens, the parfocal point remains unchanged and delivers no image shifting occurs.
The two advantages above-mentioned are extremely significant ones on the occasion of configuring a microscope optical system, and it has been said for a long time that “an infinity-corrected optical system is an ideal microscope optical system”. If you make the most of these advantages, you can configure an optimal optical system by optionally taking in and out an intermediate lens unit within the parallel beam section between the objective lens and tube lens.

2. 10x/20mm wide field eyepiece
Full-coated wide-angle eyepiece, low-distortion multi-layer coating ultra-wide field, 10 times magnification 20mm wide-field observation, the effect is clearer
3. Objectives for flat images
ICOE has developed the infinite plan achromatic objectives, which features superior image flatness for BM36U, Chromatic aberration and field curvature are corrected over the entire field of view. Images are clear and bright at every magnification. The BM36U provides first class optical quality at a modest price.
4. Anti-mold design
Anti-mold paint and an anti-mold tablet are used in the objectives, eyepieces and tubes to prevent mold forming in high-humidity environments.
5. Binocular and trinocular heads are available
The BM36U adopt Siedentopf-type head that provides a constant and accurate tube length. Both binocular and trinocular are available. A digital camera can be attached to the trinocular tube.
6. Observation with comfort
The tube is inclined at 30°, allowing comfortable viewing in a natural posture. By simply swinging the front part of the tube, the user can change the eye-point height. With a pupillary distance is 62.5mm, for example, it can be moved 34mm upward or downwards. In addition, the interpupillary distance adjustment from 50~75mm and the diopter adjustment ring are designed to accommodate a wide range of operators.
7. Smooth rotation quadruple nosepiece
The high-quality revolving nosepiece has a superior internal detent click-stop mechanism. A knurled elastic covered grip around the base of the nosepiece makes the nosepiece easy to rotate and eliminates the need to touch the objectives.
8. Double-plate mechanical stage
The built-in stage has a double-plate mechanism with an XY dual travel control. The large, flat stage surface facilitates easy specimen handling. Because the height of the X-axis guide rail is level with the stage surface and the stage surface is flat and smooth glass slides move easily over the surface. A spring-loaded slide holder is included.
The N 1.25 Abbe condenser comes with an aperture diaphragm to make operations quick and easy, ensuring perfect specimen images. The condenser position can also be adjusted.
10. Coaxial coarse/fine focus knob
The coaxial coarse/fine focus knob is comfortably located at desk-height level. The focus knob and the stage handle are ergonomically designed and are located equidistant from the operator, meaning they can both be easily adjusted from a normal sitting position. In addition, the torque of the coarse focus knob can be adjusted.
11. High-intensity LED Illumination
ICOE microscope’s LED illumination provides enough brightness for bright-field, phase contrast observation. With a fly-eye lens in the illuminator, uniform brightness is provided in the entire field of view. Using environmentally friendly long-life LEDs, LED illumination boasts a long lifetime of 60,000 hours and reduces the need for frequent lamp replacement. A halogen illumination model is also available.
