Spot Light for stereo microscope

thingiverse

I recently acquired a pre-owned stereo microscope, an SZ model manufactured by Olympus and dating back 30 years. Since the microscope lacked in-house lighting capabilities, I took matters into my own hands to rectify the situation. This particular scope is specifically designed for soldering electronic circuit boards. In typical stereoscopic microscopy applications, ring lights are commonly employed for illumination purposes. However, when utilizing a ring light to illuminate printed circuit boards, the surface of the PCB often appears excessively bright and difficult to discern. To circumvent this issue, I opted for a spotlight system instead. The LED light bulb used in this setup is of the T20 type, typically utilized in automotive applications. For the hood, I repurposed a cut coffee bottle. The butterfly screw employed in this assembly measures M6. The filament used in this design is made from ABS material.
