4 Achromatic Lens is an achromatic consists of a positive low-index Crown Glass lens element cemented to a negative high-index Flint Glass lens element. The elements are chosen so as to cancel chromatic abberration at two well-separated wavelengths, usually in the blue and red region of the spectrum. Focal length is constant at those two wavelengths and focal length shifts are virtually eliminated across the visible wavelengths. One frequent use is to achieve diffraction limited focusing of a laser beam. Negative Achromats are typically used when there is a need to eliminate chromatic aberration. In addition to reducing chromatic aberration at the design wavelengths, sphericalaberration and coma are greatly reduced.

5 Prism Wedge prism Roof prism/Amici prism Beam splitter Cube Prisms are blocks of optical material with flat polished sides arranged at precisely controlle angles to each other, which deflect, deviate and rotate beams of light as well as dispersing their wavelengths. Tempotec offers many types of high precision prisms.

Standard and broadband antireflection coatings are available upon request, see our standard optics components above. Wedge prism

7 Amici prism, named for the astronomer Giovanni Amici, is a type of compound dispersive prism used in spectrometers. The Amici prism consists of two triangular prisms in contact, with the first typically being made from a medium-dispersion crown glass, and the second a higher-dispersion flint glass. Light entering the first prism is refracted at the first air-glass interface, refracted again at the interface between the two prisms, and then exits the second prism at near-normal incidence.

The cemented face of one prism is coated. Before cementing, with a metallic or dielectric layer having the desired reflecting properties, both in the percentage of reflection and the desired color. The absorption loss to the coating is minimal and transmission and reflection approach 50%. Beamsplitter cube

Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications. Cylindrical lens

11 Filters are designed by their manufacturers to transmit or absorb different wavelengths of light. And they are widely used in scientific experiments and industrial applications where that change is necessary.

Different thin line direction should use the rightness OLPF to remove. Also for the different model number of CCD, CMOS photo sensor parts have some differences on the specification, for compromise the different model number and the low pass effect, so it need to be used various dissimilarity incise angle (such as 45°, 0°, 90° and WPL), and design a combination of low pass filter which contain “layer, thickness and IR CUT”,then we can clean the noise which bring form screen. OLPF Filter

13 Color separation filters, also known as dichroic filters, are designed to separate visible light into usable spectrum for such applications as: color correction, light balancing, control systems, studio and architectural lighting, display systems, color film processors, color photocopiers, color television cameras and many more applications.

15 IR-CUT Filter is the key part for digital mobile telephone with photographic lens, PC cameras, telephone with image etc. It’s mainly is that the optical glass’ surface will be done a coating with IR CUT, it only let the light-wave in stated scope to pass. Add the IR-CUT Filter between lens and CCD or CMOS image sensor, can effectively to repress the wave disturbance which cause by the pass of the light-wave whose frequency is higher than CCD or CMOS image sensor, and also it can repress infrared light-wave, then make the image more clearly and stability.

Aspherical lenses are used to reduce certain types of aberration typically showing a much clearer picture than their traditional lens counterparts Aspherical lens

19 Its properties are much better than the multi-order waveplate because of its thinner thickness (less than 0.5mm). Better temperature (380C), wavelength (1.5nm) and incident angle (4.50) bandwidth and high damage threshold make it widely used in common application. Also, it is economical.

20 Rod Lenses are highly polished small diameter rods made of optically transparent homogeneous materials. A carefully controlled manufacturing process produces rods (or fibers) with precise diameters and unsurpassed surface quality. Optical performance is similar to a cylinder lens. Collimated light passing through the diameter of the rod will be focused into a line.

21 Fisheye lens is a wide-angle lens that takes in an extremely wide, hemispherical image.The focal lengths of fisheye lenses depend on the film format.Fisheye lenses achieve extremely wide angles of view by forgoing a rectilinear image, opting instead for a special mapping (for example: equisolid angle), which gives images a characteristic convex appearance. A panorama by rotating lens or stitching images (cylindrical perspective) is not a fisheye photo. Fisheye lens showed in picture is used for Sanyo projector XM-1000C,5000 Lumen.We could manufacture and design kinds of fisheye lens as reqeusted. Projector fisheye lens and Sphere screen
