Dichroic optical filters consist of thin film dielectric coatings on glass and exhibit sharp transitions between transmitted and reflected wavelengths. dichroic lens are similar to traditional interference filters but differentiate themselves by reflecting all unwanted wavelengths. Consequently our dichroic range also offers minimal absorbance characteristics.

 

Our dichroic filters are available in longpass, shortpass, bandpass, bandblocking and colour correction types over a range of wavelengths. Dichroic shortpass and longpass filters can also act as hot and cold mirrors respectively.

 

Dichroic filters can divide natural light from a certain wavelength into two parts, one of which passes through, and the other is reflected or absorbed. Filters that allow longer wavelengths of light to pass through are referred to as long wave pass filters, and filters that allow shorter wavelengths of light to pass through are referred to as short wave pass filters.

 

The desired spectral range can be achieved by using different dichroic mirror.

Colored Glass Filter

 Colored Glass Filter

colored glass light filters is a performance of the color of the optical filter glass, which absorbs undesired through the band of the way, to precisely select the range of light waves to pass.

 

Tinted glass is a lower cost solution than a schott color glass filters, and tinted glass can be easily extended over a wide band. It is widely used in laser protection, industrial measurement and environmental measuring instruments.

Bandpass Filter

 Band pass filter can separate a band of monochromatic light, the ideal transmittance of band-pass filter through the bandwidth is 100%, while the actual band-pass filter pass band is not the ideal square. The actual band-pass filter generally has a center wavelength λ0, a transmittance T0, a half width of the pass band (FWHM, a distance between two positions where the transmittance in the pass band is half the peak transmittance), the cutoff range and other key parameters to describe.

 

Band-pass filter is divided into narrow-band filter and broadband filter.

 

In general, a very narrow bandwidth or high cut-off steepness will make the product more difficult to process; meanwhile the pass band transmittance and cut-off depth is also a contradictory indicator

 

Hyperion Optics’ bandpass filter design are composed of a stack of equally spaced dielectric layers. The number of layers and thicknesses are calculated with excellent cut-off depth (typically up to OD5 or higher), better steepness and a high transmittance (70% narrowband, 90% broadband).

 

Applications:

1. Fluorescence microscopy

2. Raman fluorescence detection

3. Blood component testing

4. Food or fruit sugar detection

5. Water quality analysis

6. Laser interferometer

7. Robot welding

8. Astronomical telescope observation celestial nebula

9. Laser ranging and so on

Optical Dome

 Glass domes are widely used for commercial applications which require protective boundary between different environments; domes perform as windows, providing protection to electronic sensors or detectors without sacrificing field of view.

 

Composed of two parallel optical surfaces, domes have no optical effect on design optical path. In lead element in an optical system, a dome is exposed to the environment, N-BK7 is good choice for visible to near infrared lead applications, which will withstand wind and rain erosion. Typically in single-use defense applications and ocean exploration. Shapes can vary from hemispheric to custom size with coatings.

 

At Hyperion Optics, we have strict control of wall thickness variation spec by utilizing most reliable deterministic CNC machine tools, we grind and polish optical glass, fused silica and zinc sulfide for applications range from visible to infrared.

 

N-BK7 and H-K9L domes: N-BK7 domes are available directly from stock, and are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability. Our custom K9 Dome are practically free from bubbles and inclusions, making them perfect for high performance visible applications.

 

UV fused optical dome: For applications operating in the deeper UV range, we offer a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures. Our Corning 7890 2G and Spectrosil 2000 fused silica both offer over 85% transmission at wavelengths as low as 185nm.

 

ZnS Dome: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and infrared-guided missile applications.
