Diffractive Optical Element (DOE)
Description:
LD Collimators & Diffractive Optics: Beam-Splitter
Diffractive beam splitters excel in providing precise control over the angles and intensities of split beams, making them ideal for high-precision applications such as laser systems, optical metrology, and advanced display technologies. Their compact and lightweight design, combined with wavelength specificity and high efficiency, ensures they perform exceptionally well in portable devices and systems where space and weight are critical. Additionally, their ability to generate complex beam patterns enhances their utility in spectroscopy and other fields requiring detailed spectral analysis.
