BX61 Gets You the Image You Want

Darkfield

Surface mounting board

Darkfield lets you observe scattered or diffracted light from the specimen. The light from the lamp travels through ring-form illumination optics in the illuminator and is focused on the specimen. The light from the specimen is reflected only by imperfections in the z axis. The user can identify the existence of even a minute scratch or flaw down to the 8 nm level--smaller than the resolving power limit of an optical microscope. Darkfield is ideal for detecting minute scratches or flaws on a specimen and examining mirror surface specimens, including wafer.

Polarized Light

Asbestos

This microscopic observation technique utilizes polarized light generated by a set of filters (analyzer and polarizer). The characteristics of the sample directly affect the intensity of the light reflected through the system. It is suitable for metallurgical structures (i.e., growth pattern of graphite on nodular casting iron), minerals, and LCDs and semiconductor materials.

Differential Interference Contrast (DIC)

Magnetic head

DIC is a microscopic observation technique in which the height difference of a specimen not detectable with brightfield becomes a relief-like or three-dimensional image with improved contrast. This technique, based on polarized light, can be fitted to your needs with a choice of three specially designed prisms. It is ideal for examining specimens with very minute height differences, including metallurgical structure, minerals, magnetic heads, and hard-disk media and polished wafer surfaces.

Fluorescence

Particle on semiconductor wafer

This technique is used for specimens that fluoresce (emit light of a different wavelength) when illuminated with a specially designed filter module that can be tailored to your application. It is suitable for inspection of contamination on semiconductor wafers, photo-resist residues, and detection of cracks through the use of fluorescent dye. An optional apochromatic lamp house collector lens system can be added to compensate for chromatic aberrations from visible light to near-infrared light.

Transmitted Light Observation

LCD color filter

For transparent samples such as LCDs, plastics and glass materials, true transmitted light observation is available by using a variety of transmitted light condensers. You can examine your samples in brightfield, darkfield, DIC, and polarized imaging in transmitted light, all in one convenient system.
