Description
Lomo OI-35 Microscope Illuminator and Lomo BP Power Supply for Lomo Biolam MicroscopeKoehler-standard illumination kit for the Lomo Biolam microscope:
- Lomo BP power supply (transformer) with 220V/230V (outlet) > 8V/9V 25W (illuminator plug)
- Lomo OI-35 Koehler illuminator with field diaphragm
- illuminator plug with Lomo 8V 20W BA15d bulb
Fits microscopes including:
- Lomo Biolam
- Lomo Biolam M
- and certainly many other models (e.g., Polam)
A small, non-Koehler illuminator for these microscopes is the Lomo OI-21, which is mounted on a base like the OI-35 (and therefore does not use a mirror). The Lomo OI-19 is an external illuminator that shines onto the mirror. The Lomo OI-35 uses the same filament bulb as these two, but now allows for Koehler standard lighting.
Koehler standard lighting allows for the best image quality when working with oil immersion or phase contrast.
The last photos are an example of use.
