(3) Optional 187×166mm super large double-layer mechanical stage, two-way linear rail transmission, left and right hand positions are optional.
Safe carrying design.
The rear side of the microscope has been designed with a handle position, which makes it safe and easy when carry the whole microscope.
Koehler Illumination System
6V 30W transmitted system, presents a bright and uniform field under every magnification. New designed telecentric Koehler illumination system, working with N.A. 1.2/0.22 swing-out achromatic condenser, applies to 2X-100X observation.
Disc switching mechanism for filters
Newly designed high-precision disc switching mechanism, is easy to change filters. It guarantees the exact position of the switched filters, can be equipped with six fluorescence filters at most. Selecting driftless high-performance fluorescence filter system, ensures an accurate experiment result of FISH. High transmittance of spectrum without a cross color but a high S/N ratio, promotes dramatically fluorescence imaging contrast. The filter with stray light elimination technology, presents high contrast between image and its background, achieves the best effect of observation.
Efficient illumination system
High-graded SiO2 quartz, with the characteristics of refractory, corrosion-resistant and high UV through rate makes the illumination more uniform and brighter. High temperature resistant composite plastic, with heat insulation, effectively prevent the heat of illuminator from transferring to the body. Alterable field diaphragm with adjustable center, effectively reduce the stray light to obtain the best observation effect.
Semi-apochromatic fluorescence objectives
New professional infinity plan semi-apochromatic fluorescence objectives, the best choice for fluorescence observation. Aberration correction and large numerical aperture which is 25% bigger than ordinary objectives, present brighter and clearer image. Adopting high quality environmental protection optical materials, show excellent effect in fluorescence observation. With advanced multi-coating wide-band technology, take the obvious advantages in bandwidth and UV transmittance.
High-performance fluorescence filters
High performance fluorescence filters, high spectral transmission, good depth and gradient of spectral lines. No cross color, high S/N ratio, high image contrast. Adopting stray light eliminating technology, high contrast between image and background, creates a perfect observation effect.
Power supply for mercury lamp
New digital power control system, displaying operating time and current value, clearly show you the working state of mercury lamp.
