Our Scopium XSP-191B-LED-Plan biological microscope is a sophisticated instrument offering above-average quality at an affordable price, with a wide range of upgrade options available. Its optical components are, naturally, made of glass, with virtually no plastic used anywhere on the instrument. Its distinctive features include an enlarged frame, full Köhler illumination, more precise focusing and plan objectives.
Quality starts with the objectives
The microscope is equipped with five plan achromatic objectives, providing better edge correction than semi-plan objectives and delivering sharp, high-contrast images right to the edge of the field of view. The standard configuration includes 4x, 10x, 20x, 40x and 100x objectives, which can be easily replaced thanks to their DIN-standard mounting. The spring-loaded design of the 40x and 100x objectives protects the specimen slide from accidental breakage. Three wide-field plan eyepieces (WF10x, WF12.5x and WF16x) are available for the microscope, allowing you to tailor the magnification to your needs.
LED illumination for outstanding colours
The specimen slide is illuminated by an integrated 3 W LED light, which outperforms older halogen bulbs in many respects: its colour temperature provides a more contrast-rich image, while its illumination is more uniform. Another significant advantage is that it does not heat up and consumes less power. The illumination can be fine-tuned in several ways: its intensity can be adjusted using a control knob and an iris diaphragm with a diameter range of 2 mm to 30 mm, while the focus can also be adjusted with the N.A. 1.25 Abbe condenser. These features enable the use of the Köhler illumination method.
Precision above all
In addition to the standard focusing mechanism, the microscope features a graduated fine-focus control on the same axis, with 0.002 mm increments, ensuring that the image can always be brought into razor-sharp focus. The enlarged mechanical stage features two-axis fine movement and can be adjusted with 0.01 mm precision, eliminating the need to touch the specimen by hand and thereby preventing vibrations to the microscope. All moving parts are free from backlash, ensuring comfortable operation.
Binocular head for extended observation
For those serious about observing the microscopic world, binocular viewing enables comfortable observation over extended periods. The viewing head is inclined at 30° and can be rotated through 360°, making it comfortable to use from any direction. A camera can be attached after removing one of the eyepieces.
The standard package also includes yellow, green and blue filters, as well as a durable dust cover to protect the microscope when not in use.
