工作原理
The Lens/Collimator operates on optical refraction principles. It captures the diverging light emitted from the laser diode's active region and redirects it through precisely curved lens surfaces. Aspheric lenses are commonly used to correct spherical aberrations and achieve high collimation efficiency. The collimator's focal length and numerical aperture are matched to the laser diode's emission characteristics to produce a beam with minimal divergence (typically <1 mrad) and uniform intensity profile.

常见问题

What is the difference between a lens and a collimator in laser diode applications?

A simple lens focuses or diverges light, while a collimator is specifically designed to produce a parallel beam from a point source. In laser diode systems, collimators often incorporate multiple lens elements to correct asymmetries in the diode's output beam.

How do I select the right Lens/Collimator for my laser diode?

Key selection parameters include: matching numerical aperture to diode emission angle, wavelength compatibility, required beam diameter, power handling capacity, and mechanical mounting compatibility. Always consult the diode's datasheet and consider thermal effects in high-power applications.

Can Lens/Collimators be used with different wavelength laser diodes?

Most are optimized for specific wavelength ranges due to anti-reflection coatings and material dispersion characteristics. Using outside specified ranges reduces efficiency and may cause damage. Broadband AR coatings are available for multi-wavelength applications.
