Key Features for PCR Applications

Precise Wavelength Control: Tight binning ensures optimal excitation for specific fluorescent dyes (e.g., 470nm for FAM, 525nm for HEX).
High Radiant Flux: Available in multiple power grades (0.5W, 1W, 3W+) to meet varying sensitivity requirements.
Superior Thermal Management: Ceramic substrate and vertical structure design minimize thermal resistance, ensuring wavelength stability during long-term operation.
Wide Spectral Coverage: From germicidal UVC (265-280nm) to IR sensing (850-940nm) in a compact 3.5×3.5mm package.

Why Choose Our 3535 PCR LEDs?

1. Unmatched Spectral Precision

Our LEDs offer narrow spectral widths (as tight as ±3nm), crucial for minimizing crosstalk between fluorescence channels in multi-color PCR systems. From UV excitation to IR detection, every bin is strictly sorted.

2. Robust Thermal Performance

Designed with a ceramic substrate and vertical heat dissipation structure, these LEDs maintain stable wavelength output even under high-current driving conditions (up to 1000mA), ensuring consistent experimental results over thousands of cycles.

3. Compact & Flexible Integration

The industry-standard 3535 package (3.5 x 3.5 mm) allows for dense array layouts in portable PCR devices and handheld analyzers, supporting various viewing angles (60°, 120°) to match your optical design.

Target Applications

- Real-Time PCR (qPCR) Instruments: Precise excitation sources for SYBR Green, TaqMan probes, and other fluorophores.
- DNA/RNA Analysis Systems: High-stability UV and Visible light sources for spectrophotometry and quantification.
- Point-of-Care Testing (POCT): Low-power, high-efficiency options for portable diagnostic devices.
Biosensors & Immunoassays: Specialized IR (850/940nm) and UV-C (265/275nm) LEDs。
