Page 4: Before Use
1 Before use 1.1 General notes You must open the packaging carefully, to make sure that none of the accessories in the packaging fall on the floor and get broken. In general, microscopes should always be handled carefully because they are sensitive precision instruments. -
Page 5: Storage
1.3 Storage You should ensure that the device is not exposed to direct sunlight, temperatures which are too high or too low, vibrations, dust or a high level of humidity. The ideal temperature range is between 0 and 40°C and a relative humidity of 85% should not be exceeded. -

Special cleaner for optical lenses Special optical cleaning cloths Bellows Brush When handled correctly and checked regularly, the microscope should give many years of efficient service. Should repairs still be necessary, please contact your KERN dealer or our Technical Department. OLE-1_OLF-1-BA-e-1510... -

Page 11: Assembly
Three colour filters are included in the scope of the delivery of all microscopes within the series OLE-1 and OLF-1. Blue, green and grey. In order to use one of them it can be simply inserted into the ring holder of the field lens. -
Page 12: Operation
5 Operation 5.1 Getting started The very first step is to establish a power connection using the mains plug. You should first adjust the dimmer to a low level, so that when you look through the eyepiece for the first time, your eyes are not immediately subject to a high level of light. -
Page 13: Pre-) Focussing
5.2 (Pre-) focussing When you are observing an object, you must have the correct distance to the objective to achieve a sharp image. In order to find this distance at the beginning (without other default settings of the microscope) place the objective with the lowest magnification in the beam path, look through the right eyepiece with the right eye and turn it slowly using the coarse adjustment knob (see illustration). -
Page 14: Adjusting The Interpupillary Distance
5.3 Adjusting the interpupillary distance (For binocular devices) With binocular viewing, the interpupillary distance must be adjusted accurately for each user, in order to achieve a clear image of the object. While you are looking through the eyepieces, use your hands to hold the righthand and lefthand tube housing firmly. -
Page 15: Adjusting The Magnification
5.5 Adjusting the magnification After prefocussing has been carried out using the objective with the lowest magnification (see section 5.2), you can then adjust the overall magnification using the nosepiece, as necessary. By turning the nosepiece you can bring any one of the four other objectives into the beam path. -
Page 16: Adjusting The Illumination
5.6 Adjusting the illumination To make sure that perfect image results are achieved during microscopic observation, it is important that the direction of light of the microscope is optimised. The necessary control elements for this are the aperture diaphragm and field diaphragm. -
Page 17: Using Eye Cups
5.7 Using eye cups The eye cups supplied with the microscope can basically be used at all times, as they screen out intrusive light, which is reflected from light sources from the environment onto the eyepiece, and the result is better image quality. But primarily, if eyepieces with a high eye point (particularly suitable for those who wear glasses) are used, then it may also be useful for users who don’t wear glasses, to fit the eye cups to the eyepieces. -
Page 18: Using Oil Immersion Objectives
5.8 Using oil immersion objectives The 100x objectives of the OLE-1 and OLF-1 series are objectives which can be used with oil immersion (they are always marked with the word “OIL”). Using these generates a particularly high resolution for microscopic images. -
Page 19: Changing The Bulb
6 Changing the bulb Before changing the bulb the device must be switched off and unplugged. To change the bulb, tip the device carefully to the back or side. When doing this, please make sure that all microscope components are firmly fixed. The bulb holder is on the underside of the device. -
Page 20: Trouble Shooting
8 Trouble shooting Problem Possible causes The mains plug is not correctly plugged in There is no power at the socket The bulb does not light Defective bulb Defective fuse The bulb blows immediately The specified bulb or fuse has not been used The aperture diaphragm and/or field diaphragm are not opened wide enough The selector switch for the beam path is set... - Page 21 Problem Possible causes The aperture diaphragm is not opened wide enough The condenser is too low The objective does not belong to this microscope Blurred details The front lens of the objective is dirty An immersion object has been used without Bad image immersion oil Bad contrast...
