Halogen light source characteristics of trinocular microscope

Halogen light source is one of the common light sources in trinocular microscopes. Due to its unique optical properties and ease of use, it is widely used in biology, materials science, education and other fields.
High brightness: Halogen lamps can provide relatively strong light sources, making samples clearer during observation. In experiments requiring high-contrast observation, halogen lamps can significantly improve image quality.
Stable color temperature: During the operation of halogen lamps, the color temperature changes little, and it can maintain consistency under different experimental conditions, which is suitable for long-term observation and photography.
Economical: Halogen lamps are relatively low in cost and easy to replace, allowing laboratories to have efficient lighting equipment even with limited budgets.
Wide range of application: Due to its bright and stable light source, halogen lamps are suitable for a variety of observation techniques, such as transmitted light, bright field microscopy, and phase contrast microscopy.
Disadvantages
Despite the many advantages of halogen lamps, there are also some limitations. It has a high heat generation, and long-term use may cause the temperature inside the microscope to rise, thereby affecting the stability of the sample, especially biological samples. Halogen lamps have a relatively short lifespan, usually between 200 and 500 hours, and need to be replaced regularly when used frequently, increasing maintenance costs and workload. In addition, halogen lamps produce instantaneous high light intensity when turned on, which may cause damage to certain light-sensitive samples.
