2W Led Round Plate for Microscope 50mm Plate Illuminator NXP-295
The NXP-295 is a 2W round LED plate illuminator with a 50mm diameter, designed to fit on microscope stands for transmitted light inspection.

Product Overview
The NXP-295 is a 2W round LED plate illuminator with a 50mm diameter, designed to fit on microscope stands for transmitted light inspection. It operates on 90-265V AC, delivers 6400K color temperature or custom options, and provides ≥7000 lumens. The unit uses a glass and aluminium housing for heat dissipation and optical clarity, and connects via standard AC power. It is intended for use with biological, stereo, and metallurgical microscopes requiring consistent, even illumination under the stage.

Key Benefits
- 50mm diameter round plate fits standard microscope stage openings for transmitted light
- 2W LED delivers ≥7000 lumens at 6400K color temperature for bright, neutral white illumination
- 90-265V AC input allows use in multiple global power environments without a transformer
- Glass and aluminium housing provides stable thermal management and optical clarity
- No moving parts or cooling fans, so operation is silent and maintenance-free
- Can be mounted directly on microscope stands with standard screw or clamp fittings
- Custom color temperature options available upon request for specific material inspection needs
Application Scenarios
- Transmitted light inspection of thin biological sections or transparent materials on a biological microscope
- Surface inspection of metal foils, printed circuit boards, or thin films under a stereo or metallurgical microscope
- Consistent illumination during quality checks in electronics manufacturing for solder paste or component alignment
- Use in teaching labs where multiple students need uniform lighting on a shared microscope stage
- Low-heat, continuous illumination for long-duration observation without thermal drift
Who It Is For
- Electronics manufacturers inspecting PCBs, SMD components, and solder joints
- Teaching and research laboratories using biological or stereo microscopes
- Metallurgy and materials testing labs requiring even transmitted light
- Quality control departments needing repeatable illumination for inspection records
- Educational institutions running microscopy sessions with multiple users
Problems It Solves
- Inconsistent or dim illumination from older halogen or fluorescent stage lights causes eye strain and poor contrast
- Fixed-angle or directional lights create shadows on uneven or textured samples
- High heat from halogen lamps distorts temperature-sensitive samples or causes focus drift
- Lack of standard mounting options forces custom fabrication or unstable setups
- No option for adjustable color temperature leads to inaccurate color representation in inspection
Technical Features
- 2W LED light source with ≥7000 lumens output
- Round 50mm diameter plate for stage mounting
- 6400K color temperature standard, customizable upon request
- 90-265V AC input voltage range for global compatibility
- Glass and aluminium housing for thermal stability and optical clarity
- No external power supply required; connects directly to AC mains
- Flat, even illumination across the 50mm diameter area
- No cooling fan or moving parts, ensuring silent operation
- Designed for use with biological, stereo, and metallurgical microscopes

Customization Options
- Custom color temperature options available upon request (e.g., 4000K, 5000K, 7000K)
- Alternative power input options (e.g., 12V DC) available on request
- Mounting hole pattern can be adapted for non-standard microscope stands
- Different plate diameters (e.g., 100mm, 150mm) available in other models
Comparison With Other Options
| NXP-12 2W Square Plate Illuminator | Same 2W power and ≥7000 lumens, but the NXP-295 has a round 50mm plate instead of a 50x50mm square for better fit on circular stage openings. |
|---|---|
| NXP-14 6W Square Plate Illuminator | Higher power (6W) and higher lumen output (≥18000LM), but the NXP-295 is smaller and lower power, suitable for applications where brightness is sufficient but heat and size are concerns. |
| Halogen stage illuminator | LED version produces no heat, lasts longer, and uses less power; halogen lamps degrade faster and cause thermal drift in sensitive samples. |
Use Guide
- Ensure the microscope stage has a compatible opening for the 50mm round plate
- Mount the unit securely using the standard screw or clamp fittings provided
- Connect to a 90-265V AC outlet; no transformer or adapter needed
- Turn on the power; the LED will illuminate immediately with no warm-up time
- Adjust the microscope focus and sample position under the plate for even lighting
- For long sessions, monitor the housing temperature; aluminium housing ensures safe operation
