  • BP785-1 Bandpass Filter - Raman Spectroscopy (Laser Line Cleanup)

    BP785-1 Bandpass Filter - Raman Spectroscopy (Laser Line Cleanup)

    Raman Spectroscopy (Laser Line Cleanup)

    This is the primary application. 785 nm is a standard Raman laser wavelength. Diode lasers often emit low-level "spontaneous emission" (background light) at wavelengths other than 785 nm. This filter cleans up the laser source, ensuring only the pure 785 nm excitation light hits the sample, which is critical for detecting weak Raman signals.

    Recommended Light Sources

    • Frequency-Stabilized 785 nm Laser Diode: This is the optimal choice because standard laser diodes can drift by ~0.3 nm/°C; a stabilized source ensures the emission wavelength remains locked within the narrow 1 nm passband of your BP785-1 filter, preventing total signal loss.
    • Single-Mode 785 nm Laser Diode (with Temperature Control): A viable standard alternative, but it requires a Thermo-Electric Cooler (TEC) controller to precisely tune and maintain the laser temperature so the peak emission aligns perfectly with the filter's window.

    BP785-1 Bandpass Filter - LIDAR & Remote Sensing

    LIDAR & Remote Sensing

    Used to block solar background noise (sunlight) while allowing the specific 785 nm laser return signal to pass through to the detector, improving the signal-to-noise ratio in daylight.

    Recommended Light Sources

    • High-Power Pulsed 785 nm Laser: Generates the high-intensity pulses needed for long-range detection; utilizing a temperature-stabilized model is critical to keep the laser wavelength locked within the filter's narrow 1 nm passband, ensuring maximum signal throughput against bright solar background.

자주 묻는 질문

마운팅의 차이점은 무엇인가요?

말 타지 않은:

  • 유리로 된 광학 필터

장착됨:

  • 광학 부품 보호를 위한 매끄러운 마운트입니다. 마운트에는 나사산이 없습니다.

미터법 마운트:

  • 접두사로 M이 시작하며, 일반적으로 M25.5x0.5mm와 같이 표기됩니다. 주로 카메라 필터로 사용됩니다.

제국의 산:

  • 접두사로 SM이 붙습니다. 보통 SM1, SM05 등으로 볼 수 있습니다. 주로 광학 시스템에서 사용됩니다. (다른 장치와 연결하기 위한 SM 외부 나사산이 있습니다.)

C-마운트:

  • 자주 사용되는 마운트입니다. C-마운트는 1인치-32TPI입니다. SM1이나 M25.5x0.5mm와는 다른 제품입니다.
