LeicaLEICA DM4000 BFluorescence upright microscopeLEDAlternative solutions for fluorescent light sources

——Innovate the bottleneck of traditional light sources and create a cost-effective fluorescent light source system

1、 LeicaDM4000 BApplication scenarios of upright microscope and pain points of light source aging

LeicaDM4000 BOrthostatic microscopes are widely used in clinical practice due to their high resolution and stabilityPathological diagnosis, industrial material analysis, immunofluorescence staining observationIt plays a core role in various fields, especially in high-frequency fluorescence staining sample observation (such as tumor marker detection, paraffin section analysis). However, it relies on traditional mercury lamps/Halogen lamp light sources are exposed to the following issues during long-term use:

1. Short lifespan of light source：

• Mercury lamp has a lifespan of only200The laboratory with high frequency of use requires monthly replacement of light bulbs, resulting in extremely high single cost.

• The lifespan of halogen lamps is approximately500When the light intensity decreases rapidly, it affects the accuracy of fluorescence quantitative analysis.

2. OEM parts dilemma：

• Some Leica mercury lamp light sources have been discontinued (such asLEJ 100WMercury lamps rely on inventory or non-standard substitutes for procurement, and their reliability is questionable.

• OEM (Original Equipment Manufacturer)LEDUpgrade plan (such asEL6000External cold light sources require specialized adapters, resulting in high overall renovation costs and extremely low cost-effectiveness for old equipment.

• The ordering cycle for imported original accessories is long2-3Months, seriously affecting the daily operation of the laboratory

3. Poor user experience：

• Mercury lamp is required15Preheat for minutes, halogen lamp heats up severely, long-term use damages the sample.

4. Optical path thermal damage：

• mercury lamp/Halogen lamps generate a large amount of heat, and long-term use may accelerate the aging of the filter, further reducing the optical performance of the system.
