BRESSER DIN PL Objective 20x, Infinity

To enhance contrast according to the refraction index and the thickness of the preparations. The phase contrast set contains four different irises, four different phase contrast objectives (10x, 20x, 40x, 100x oil) and a green color filter. A collimating eyepiece allows easy aligning. This method is especially suitable for non-stained, low contrast samples (epithelium cells, amoeba, white blood cells) and will also help with visibility of bacteria. Therefore it is used in cell culture and life science where color staining cannot be used. One position of the filter holder is free. Thus the phase contrast set can also be used as a brightfield condenser with iris diaphragm. This phase contrast set fits the Science Infinity (item No.: 5760700) microscope.

The BRESSER Erudit DLX is a high-quality microscope for school, studies and hobby use. The LED illuminator and the height adjustable condenser (with diaphragm and filter holder) offer an optimal illumination. The achromatic DIN-objectives allow a very good image. The 40x and 100x objectives are resilient to save the preparation for damage. The microscope has a 360° rotatable monocular view coarse and fine focusing drive, and a coaxial mechanical desk with nonius.

NEW - now including a high-quality aperture solar-filter for safe observation of sunspots, eclipses and planet transits. Great telescope for night and solar observation.When looking at the technical data, 80mm aperture may not look too impressive. During the observation the impact of the 31 % more light gathering power in respect to a 70mm refractor are easily visible: Details are seen more clearly in the BRESSER NANO AR-80/640 NANO and from a distance of 600 million km the main cloud bands on the planet Jupiter and many Messier objects gets visible. Richfield telescope with high quality achromatic glass lens and a short focal length of 640mm. Suitable also for traveling and to observe large open star clusterns and the milky way. The telescope arrives with a wide array of accessories and almost pre-assembled - observation can start immediately. The BRESSER NANO is a light-to-medium-duty alt-azimuth mount with tripod designed to quickly and easily accept small to medium sized refractors, such as the AR-90s, AR-102s, AR-102xs and the ED-80 APO. Lightweight, fast Newtonians will also match up nicely with the BRESSER NANO AZ mount. As long as your telescope does not exceed 8 pounds and has a Vixen-Style Universal Dovetail bar for mounting the telescope to the mount head, you are good to go. The stainless steel tripod that comes standard with the BRESSER NANO AZ mount has adjustable legs and a wide foot print, which makes the tripod more stable. Spreader vanes with an acessory tray locks against the inside of the legs to secure the tripod even further, and keep vibrations to a minimum. Do you want to capture what you see ?
