Laser Microscopy

Laser Optics

Laser Microscopy is used to image samples through the use of focused laser beams. In general Laser Microscopy applications, a sample is scanned by a focused laser beam and the intensity of the reflected beam is converted to a digital image. Confocal microscopy, also known as confocal laser scanning microscopy, offers various advantages over traditional wide-field microscopy, such as enhanced resolution, targeted imaging location, and higher image depth. Common laser microscopy techniques include super-resolution microscopy, fluorescence microscopy, and two- or multi-photon microscopy.

Edmund Optics offers a range of Laser Microscopy objectives in finite and infinite conjugate styles for use with common laser wavelengths, such as those of popular laser diodes or Nd:YAG harmonics. Our TECHSPEC® ReflX™ Objectives are reflective microscope objectives that can efficiently focus laser light without introducing any chromatic aberration. These objectives feature a rugged design to withstand exposure to moderate heat or abrasion and are ideal in applications that range from FTIR spectroscopy to semiconductor inspection. TECHSPEC® High Performance ReflX™ Objectives are also available, providing better peak-to-valley transmitted wavefront and a design that allows for angles of incidence up to 45°. Mitutoyo Objectives, with excellent performance at Nd:YAG harmonics, are ideal for integration into semiconductor inspection or laser cutting applications.
