Optical Test Systems Fiber Collimator Compact 1310nm 1550nm Fiber Collimation

The miniature fiber collimator reduces the volume of traditional collimators by more than 50% through a compact lens and fiber coupling design, while maintaining high-precision optical performance. Its core adopts micro lenses with a diameter of 1mm-2mm, combined with tight fitting fiber optic packaging (outer diameter of 0.9mm/2.0mm), which can be embedded in small spaces such as micro spectrometers, endoscopic medical equipment or portable sensing systems. For example, in biomedical imaging, this design can achieve low insertion loss (≤ 0.5dB) and high transmittance (≥ 90%), while supporting single-mode (1310nm/1550nm) and multi-mode (850nm/1300nm) wavelengths, meeting the requirements of high-resolution signal transmission.

Fiber collimator: ensuring low loss transmission of fiber optic signals

The fiber collimator can significantly reduce signal transmission loss by optimizing the coupling process between the lens and the fiber. Its core lies in the 8 ° oblique angle (APC type) polishing of the lens end face, effectively suppressing end face reflection, with a return loss of ≥ 45dB. At the same time, combined with the design of non spherical lenses, it reduces aberrations and ensures the minimization of beam divergence angle (typical value 0.1 ° -0.5 °). For example, in data center optical interconnection, this design can achieve long-distance (≥ 10km) low latency transmission, while supporting parallel processing of multiple signals to avoid wavelength cross interference, making it suitable for high bandwidth, low loss optical communication networks.

Widely used in scientific research experiments and laboratories: multifunctional adaptation of fiber optic collimators

Fiber optic collimators have become standard equipment in scientific research experiments and laboratories due to their high precision and flexibility. In precision instruments such as laser interferometers and spectrometers, this design can be embedded with optical path modules and supports both single-mode and multi-mode wavelengths, meeting diverse needs from basic physics research to material characterization. For example, in quantum optics experiments, fiber collimators can achieve low insertion loss (≤ 0.5dB) and high transmittance (≥ 90%), ensuring signal integrity. At the same time, their compact structure simplifies the installation process and is suitable for laboratory environments with limited space.

High reliability fiber collimator: a solid guarantee for high stability applications

High reliability fiber optic collimators undergo rigorous environmental testing, such as vibration and temperature cycling, to ensure stable operation under extreme conditions. Its core adopts metal/ceramic packaging, with a tensile strength of ≥ 60N, and supports a wide temperature range (-25 ℃ to+70 ℃), with a mechanical stability of 0.02mrad. For example, in harsh scenarios such as industrial automation and aerospace, this design can maintain low insertion loss (≤ 0.5dB) and high return loss (≥ 45dB) for a long time, making it suitable for applications with high stability requirements, such as unmanned aerial vehicle obstacle avoidance systems and satellite communications.
