2 140 Microscopes Microscopes Microscope range The Gundlach microscope range consists of three different series of microscopes suitable for novice, intermediate and advanced teaching levels. In addition we have three basic models, DualScope and 100 FL/100 FL LED. Primomic series Simple good quality microscopes at very attractive prices. With standard achromatic objectives and optional 60x or 100x objective. Very suitable for novice students. More on page 142. Primolab series Easily operated good-quality microscopes with semiplan achromatic objectives and a good selection of accessories. Suitable for intermediate teaching and routine work in medical/veterinary practices and small laboratories. More on page 144. PrimoX series The largest and most versatile microscope in our range. With modern ergonomic design, high quality plan achromatic objectives and a very wide selection of accessories. Suitable for advanced teaching and for hospitals, clinics, medical centres, specialist laboratories, food inspection etc LED Basic microscopes Microscope, model DualScope Robust low-priced hobby/student microscope with simple optical glass objectives mounted on a revolving nosepiece. It comes with a plastic vertical stage with stage clips and a 6-hole disc condenser. The eyetube is mounted at a 45 degree angle for comfortable viewing and has a wide-field eyepiece with built-in pointer. In addition to the traditional bottom light the microscope is provided with a top light, and is thus also suited for observation of surfaces of leaves, coins, insects etc. A simple microscope ideal for hobby use and for smaller children. The simplicity of the design makes it a good choice as an introduction to microscopes or as a supplement to the traditional school microscopes.

4 142 Microscopes Primomic microscopes The Primomic range is one of the most economical choices in our selection of microscopes. These microscopes are characterized by a nice finish and good precision. With continuously variable halogen-type illumination, and DIN-standard achromatic par focal objectives this microscope series provides good value for the money. The large mechanical stage has a steady, permanent traveser and low mounted coaxial controls, a design which is usually only found in larger and more expensive microscopes. The eyepiece tube is mounted at an angle on a revolving head and in addition, the binocular model has dioptric and interpupillary adjustment. Magnification range/objective type The Primomic series microscopes are available with either 60x objective or 100x objective as the highest magnification. 60x objective Magnifies 600x combined with a 10x eyepiece, and this magnification is usually satisfactory for most preparations used in basic microscope teaching. The 60x objective does not require immersion oil and is thus very suitable for student use. 100x objective Magnifies 1000x combined with a 10x eyepiece. Required to view very small specimens (like bacteria) in detail. Requires oil immersion, careful adjustment and thorough cleaning afterwards. Suitable for advanced users, teacher microscopes etc. Microscope, Primomic, monocular Magnification: 40x to 600x/1000x Optical head: Monocular Eyepiece: 10x, wide-field Objectives: Standard achromatic objectives 4x achromatic N.A x achromatic N.A x achromatic N.A (spring front) 60x achromatic N.A (spring front) Magnification: 40x, 100x, 400x, 600x/1000x Condenser: Abbé-condenser N.A With built-in iris diaphragm and filter holder.

8 146 Microscopes PrimoX microscope The PrimoX microscope is the largest and most versatile microscope in our range. The modern ergonomic design encourages the best possible working positions. Controls for focusing and operating the mechanical stage are placed low to allow hands to rest on the bench while adjusting the microscope and the strong T-shaped stand ensures maximum stability. The top-quality par focal plan achromatic objectives are mounted in an easily operated, five-hole backward-facing revolving nosepiece, providing more working space and improved facilities for attaching lenses for phase- and polarization microscopy. A wide range of extra equipment such as dark-field equipment, phase contrast equipment, polarization equipment and photographic equipment makes it possible to create custom-made solutions for almost every purpose. The PrimoX microscope is suitable for all purposes in hospitals, clinics, medical centres, specialist laboratories, food inspection and advanced teaching wherever robust, precise and easily operated microscopes are needed.

9 Microscopes 147 Digital microscopes We are happy to present our first true digital microscope: The DigiTeach. The DigiTeach was selected because of its strong specifications which include: LED light source, 4 objectives (with the user friendly 60x objective), 1.3 MP camera, good software and modern design. The specifications are very close to those of the popular Primomic-series characterized by good optics, good precision and a fair price. The improvements are mainly found in the light source, design and the built-in camera Digital microscope, DigiTeach This elegantly designed digital USB-microscope is very suitable for both teacher and student use. It is equipped with continuously variable LED light powered by an external power supply. The 60x objective is used without immersion oil, and this makes the microscope very easy to use and minimizes cleaning of the lenses after use.

14 152 Microscopes Zoom stereo microscopes Zoom stereo microscopes are the preferred choice when you use a stereo microscope for routine inspection or for more careful examination of insects, plants etc. The optical system gives a continuously variable magnification so it is possible to use exactly that magnification that gives the best view. This can be a great advantage, when certain details need to be checked on insects etc. or you want to adjust the field of view to a certain size in order to see the complete object. Zoom stereo microscopes are therefore very suitable for high schools, universities and inspection work during production Zoom stereo microscope, Primozoom ll Robust zoom stereo microscope with 45 degree inclination of head for viewing comfort and eyepieces with both interpupillary and dioptric adjustments. Eyepieces include soft eye cups to keep prolonged viewing comfortable while blocking peripheral light. High precision lenses make it possible to use the zoom stereo microscope for long periods of time without eyestrain. Stable stand with column and wide base with rounded corners promotes a good working position. Magnification: 10x to 40x, continuously variable. Can be increased to 80x with accessories. Eyepieces: 10x wide-field with 16.5 mm aperture.

16 154 Microscopes Extra magnification for Stereozoom Extra magnification can be achieved either by replacing the original eyepiece with an eyepiece with larger magnification or by attaching an auxiliary lens to the main objective. Auxiliary lenses give you the best optical quality, but working distance is reduced. To keep a large working distance, use an eyepiece with larger magnification. The optical quality is not quite as perfect as for the auxiliary lens but working distance is the same Eyepiece 15x, Stereozoom Eyepiece 20x, Stereozoom Auxiliary lens attachment 0.5x, Stereozoom Auxiliary lens attachment 1.5x, Stereozoom Auxiliary lens attachment 2x, Stereozoom Other accessories for Stereozoom: Bulb 6V/15W, halogen w. reflector, Stereozoom (top light) Bulb 6V/12W, halogen, Stereozoom (bottom light) Micrometer eyepiece 10x, Stereozoom Photo adapter, SLR-cameras (T2-adapter not included) Polarization set, Stereozoom Photo eyepiece tube For trinocular Stereozoom P-TR and IT-TR.
