BRESSER Microscope Cutlery Solingen Steel (Refurbished)

Slides and cover glasses are an indispensable accessory which has also impact on the image quality. For most biological microscopes, the cover glass thickness is an important optical parameter, which is therefore included in the optical design and, if so, printed on the sleeve of every objective. You can usually see the number 0.17 which is the thickness in millimeters. For demanding applications in the laboratory, or for microphotography, using cover glasses with the desired thickness and high quality is necessary.The cover glasses included in the set are made of Boro 3.3 glass and are standardized to a thickness of 0.16-0.19mm. So they match the desired 0.17mm really good and give the best possible image quality. These Boro 3.3 cover glasses are pure white, without streaks and are pre-cleaned and ready to use. They are also especially suitable for fluorescence microscopy.The slides are made of soda lime glass, and have ground edges for safe handling. They have a matte field for writing on both sides (top and bottom). Slides and cover glasses are packed separately and in a vacuum sealed bag, containing moisture absorbent. They can be stored for a long time without loss of quality from hydrolysis and are easy to take out.

Microscope slides with a micrometer scale are used for the calibration for measurements.They are used in combination with a micrometer eyepiece or a measurement software (for cameras) in order to measure preparations. The broad scale is suitable for lower magnifications, the fine scale for higher magnifications.

Please note that refurbished items generally come with a 12-month warranty.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.The combination of large aperture and short focal length predestine the BRESSER Messier AR-152S for the observation of large celestial objects. Experience the famous globular cluster M 13 in the constellation Hercules: Thousands of pinpoint stars stand before a black sky like so many diamonds spilled onto black velvet. Equipped with nebular filters you can watch the Gulf of Mexico in the North America Nebula and all the other celestial objects that Charles Messier listed in 1781. The compact size of the Messier AR-152S combines outstanding tranportability, high light gathering power and low weight for a telescope of this aperture. The special four lens construction delivers a better perfomance than a classical two lens achromat of this focal length. This telescope is only an optical tube without mount and tripod.FEATURESOptical design: refractor telescopeLens diameter: 152 mm / focal length: 760 mm / F/5Maximum recommended magnification: 254xTelescope for night and solar observationHigh quality BRESSER refractor opticsUniversal telescope for planets, double stars, planetary nebulae and deep-skyExcellent focuser with 2,5" (65 mm) open diameterFour lens construction8x50 straight through viewfinder reticleoptimized finder socket for comfortable useCradle rings with handle and integrated piggyback camera holder (1/4 thread)Smartphone camera adapter for sky navigation includedUniversal 44 mm Dovetail plate with stainless steel rail (fits LXD75/Great Polaris/EQ5)50,8 mm (2") to 31,7 mm (1,25") adapter with integrated T2 thread (T2-adapter ring for your camera is needed)Backfocus: 150 mm behind Hexafoc with attached 2" eyepiece adapterCollimatable lens cellSCOPE OF DELIVERYOptical Tubeaperture solar-filter26 mm Super Plössl eyepiece (31.7 mm / 1.25")31,7 mm (1.25") diagonal mirrorintegrated 31.7 mm and T2 adaptertube rings with universal 44 mm Dovetail plate with stainless steel rail (fits LXD75/Great Polaris/EQ5)handle with camera holderSmartphone adapter for celestial navigation 8x50 Viewfinderastronomy PC software Stellariumrotatable star map

The immersion oil is used as a medium to get focus with a 100x oil objective. Without this oil it's not possible to get a sharp image.Volume: 5 ml
