		The reflected light from the disc is separated by the dichroic mirror into laser light beams of the first and second wavelengths and, in respect of at least one of the return light beams, the phase difference between the P-and S-polarization components is compensated by a phase compensation unit.
		mirror 18 may occasionally be provided between the dichroic mirror 16 and the object lens 17 for bending the light path of the laser beam in an orthogonal direction depending on the necessity imposed by the specific arrangement of optical components.
		In respect of one of the return laser light beams from the dichroic mirror 16, that is, the laser light with the wavelength of 780 nm, the phase difference between the P-polarization component and the S-polarization component is compensated by the Phase compensation plate 32.

		In a fluorescence microscope, a dichroic mirror is used to separate the excitation and emission light paths.
		Ideally, the wavelength of the dichroic mirror is chosen to be between the wavelengths used for excitation and emission.
		The dichroic mirror is a key element of the fluorescence microscope, but it is not able to perform all of the required optical functions on its own.

		In many of the current reflected light fluorescence illuminators, the exciter filter, the dichroic mirror, and the barrier filter are all incorporated into a single cube as illustrated in Figures 1 and 6.
		The function of the cube is to employ the excitation filter to tailor-make the excitation light reaching the fluorochrome; to ensure maximum reflection of the desired excitation light by the dichroic mirror; and finally to employ the barrier filter to pass the desired emission wavelengths yet block unwanted excitation light or specific unwanted emission wavelengths.
		It should be kept in mind that the individual elements (the exciter filter, barrier filter, and dichroic mirror) from the cubes of one manufacturer may sometimes be adjusted to fit into the cubes of another.

	LRIS-B Overview (Site not responding. Last check: 2007-10-14)
		Wavelengths shortward of the dichroic cutoff (the dichroics are coded by the wavelength of light that corresponds to the 50% point in transmission/reflectance; e.g., the D500 will pass half of the 500 nm photons into the red camera and reflect the other half into the blue camera) are reflected into the blue spectrograph.
		Dichroic beam splitters invariably produce low frequency ``wiggles'' in the efficiency of transmitted and reflected light that can be noticed in high S/N spectral observations; these can be removed through flat fielding.
		The dichroics produce no noticeable shift in the focus for the red side of the spectrograph, while there are very small shifts in optimum focus of the blue side spectrograph camera that depend on the chosen dichroic.

	Encyclopedia of Laser Physics and Technology - dielectric mirrors, diode bars, diode-pumped lasers, dispersion ...
		A dichroic mirror is a laser mirror with significantly different reflection or transmission properties at two different wavelengths.
		The cavity mirrors of a laser are almost always dielectric mirrors, because such devices routinely achieve a very high reflectivity of larger than 99.9%, and their limited reflection bandwidth can be convenient because it allows to transmit pump light (at a shorter wavelength) through a folding mirror of the cavity.
		silver mirrors, with which we are familiar from the household: dielectric mirrors are usually quite transparent to visible light and shine in colors which depend on the angle of view.

	Dichroic Mirrors
		Laser dichroic mirrors must have defect free surfaces and high damage threshold coatings.
		Our laser dichroic mirrors are thin film stacks which form an edge filter on one face of the mirror and an anti-reflection coating on the other face.
		When specifying a dichroic mirror remember that the cut-off has a distinct slope and that the reflection region is limited.

		Suchdevices include mirrors and filters, usually treated with optical coatings,which are designed to reflect light over a certain range of wavelengths, and transmit light which is outside that range.
		There are also parabolic concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror.
		Early mirrors consisted of a plate or sheet of polished metal, often silver or copper when the reflected image was forviewing (such as for personal grooming) but also of other metals when only the intensity of reflected light was important.

		The dichroic mirror of the emission cube is designed to cut-on within 10 nm to the red of the monochromator’s narrow band excitation, while the dichroic mirror of the excitation cube cuts-on at a wavelength just to the blue of the selected emission wavelength.
		Schematically, the dichroic mirror is colored green to depict a transmission cut-on in the green, which reflects the blue excitation downward and transmits the red emission upward.
		The dichroic mirror in the excitation cube (orange cut-on) is designed to block a greater range of wavelengths, extending from the blue to just short of the observational wavelength, in order to efficiently reflect the exciting light during a scan.

	United States Patent Application: 0030090792
		In some conventional devices, long IR pathlengths were used to convey the laser energy between a laser source 10, generally at the back of the microscope, through a fluorescent cavity 12, on to a dichroic mirror 14, and through an objective 16 to the target.
		The exit of the fiber-optic cable 32 acts as a laser source, and the beam passes through a collimating lens 34, which may be, for example, an aspheric or a GRIN lens, and reflects from a dichroic mirror 36 to provide the required almost-parallel beam into the objective 30.
		The dichroic mirror 70 reflects the wavelength.lambda.=1480 nm radiation beam along the optic axis and up into the objective 54, in a direction opposite to the image beam light.

		Jeff - To quote form the RT300 Instruction Manual: "Dichroic mirror heat reducing system - to remove heat without color distortion." Directly behind the mirror, a spring-clipped sheet-metal bracket would appear to absorb the IR heat, and a couple of slots nearby are probably part of the fan duct-work for cooling.
		Besides being fully Kodak Carousel compatible (including their dissolve units), the RT300 dichroic mirror system was reported to submit the slide itself to one of the lowest temperatures of any projector.
