Page 4: Before Use
Suitable replacement fuses are included with the delivery. When carrying out any procedures whereby you come into contact with the electrical system of the device, such as, for example, changing the bulb or fuse, only carry out these procedures when the power is disconnected. OBD-1-BA-e-1510... -
Page 5: Storage
The best way to store accessories which consist of optical elements, such as, for example, eyepieces and objectives, is in a dry box with desiccant. OBD-1-BA-e-1510... -
Page 6: Maintenance And Cleaning
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. OBD-1-BA-e-1510... -

Page 11: Assembly
4.4 Colour filter A blue colour filter is already an integral part of the microscopes of the series OBD-1. It is fitted underneath the field diaphragm. In order to use suitable filters, these can simply be placed in the ring bracket of the field lens. -

(see illustration on the left). To move the sample into the beam path, you must use the adjustment wheels on the right of the angle table (see illustration on the right). You can position a total of two object holders at the same time. OBD-1-BA-e-1510... -
Page 13: Pre-) Focussing
Important: In order to avoid damaging to the focussing system, the left and right adjustment wheels for the coarse and fine adjustment knob must never be rotated at the same time in opposite directions. OBD-1-BA-e-1510... -
Page 14: Adjusting The Interpupillary Distance
2. Then look through the left eyepiece with the left eye and use the dioptre adjustment ring to focus the image. To do this, you just need to turn the ring in both directions (see illustration), to find out where the image is at its most focussed. OBD-1-BA-e-1510... -
Page 15: Adjusting The Magnification
If you have focussed the object to be observed for a specific magnification, then if you select the objective with the next greatest magnification, then the object will be slightly out of focus. Use the fine adjustment knob to make a slight adjustment and restore the focus. OBD-1-BA-e-1510... -
Page 16: Adjusting The Koehler Illumination
If, as with the devices in the KERN OBD-1 series, the lighting can be set in accordance with Koehler, the result is homogenous illumination of the slide and avoidance of disruptive stray light. - Page 17 7. Possibly there is the need of re-adjusting the focus and x-y axis. 8. Observe the object. If another magnification is selected afterwards, then the Koehler illumination does not have to be reset from scratch, only the aperture diaphragm and field diaphragm need to be adjusted as required.

Page 18: Using The Camera
5.7 Using the camera The devices of the OBD-1 series are standardly equipped with heads, which have integrated digital microscope cameras. Thus images or sequences of an object can be measured or digitally documented easily. Scope of delivery: USB cable... -
Page 19: Using Eye Cups
In order to maintain hygiene, we would therefore recommend that you clean the eye cups regularly (e.g. with a damp cloth). Eye cups High Eye Point eyepiece (identified by the glasses symbol) OBD-1-BA-e-1510... -
Page 20: Using Oil Immersion Objectives
5.9 Using oil immersion objectives The 100x objectives of the OBD-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. To use oil immersion correctly, please follow these steps. -
Page 21: Changing The Bulb
Important: When fitting the new bulb into the socket, it must only be handled with sterile gloves or using the bulb packaging film. Grease and dust residue can have a negative effect on the light quality and service life. OBD-1-BA-e-1510... -
Page 22: Changing The Fuse
The aperture setting of the condenser must be in position PH. For its starting position, the polariser must be turned to the position in which you can see the highest level of darkness in the field of view (without object slide). OBD-1-BA-e-1510... -
Page 23: Dark Field Units
1. A special dark field condenser can be used in place of the standard condenser. This as a paraboloid construction and also meets the requirements of professional application fields, in contrast to a dark field attachment. 8.3 Phase-contrast unit OBD-1-BA-e-1510... - Page 24 (see right illustration). Depending on the preferences of the user, using a green filter can produce a more effective and pleasant image. To achieve this, the green filter must be screwed onto the underside of the PH condenser. OBD-1-BA-e-1510...
