Bulbs for optical equipment are essential for maintaining the functionality and performance of various diagnostic tools used in optometry and ophthalmology. Here are some common types of bulbs and their applications:

1. Ophthalmoscope Bulbs: These are used in ophthalmoscopes to examine the interior structures of the eye.
2. Slit Lamp Bulbs: Slit lamps, used for detailed examination of the anterior segment of the eye, require specific bulbs to provide the necessary illumination.
3. Retinoscope Bulbs: Retinoscopes, used to measure refractive error, also need specialized bulbs.
