If you need to determine the quality of an image that you have saved to your computer you can simply right click on the photo and select ‘Properties’. After clicking ‘Properties’ a dialogue box will appear. Select the ‘Details’ tab and scroll down. You will see a heading called ‘Image’. This area will tell you the dimensions of the image. An image that is 3000 pixels wide by 3000 pixels high is more suitable for print, and an image that is only 300 pixels wide by 300 pixels high will generally only work well for on-screen display.

Traffic and surveillance systems use cameras with bandpass filters and image processing to monitor and manage traffic flow and public safety.

150dpi is generally considered the minimum standard for high quality photographic reproduction in books and magazines. Newspapers often use 85dpi and the effect is clear: individual dots are visible and some detail is lost.

The bandpass 660-60 is an interference filter that blocks all wavelengths except red light in the wavelength range of 660nm. This eliminates unwanted light. The corresponding LED (660 nm) or laser with a wavelength of 660 nm is optimally visible. The steep edges of the filter allow maximum light output from the LED. Necessary light is not lost. The result is a massive increase in contrast and an improvement in image quality.

BP 540-80 HT is an interference filter with steep edges and extremely high transmission. The greenish filter is mainly used to filter out interfering light and thus increase the efficiency of measuring devices.  The filter is popular in applications such as 3D measurements, monitoring in food production or also in the field of robotics. Depending on the light source used, it significantly increases the accuracy here.

When it comes to digital displays, increasing PPI will not make your image appear any clearer, instead, it will just increase the size and loading time of your image. However, decreasing concentration of PPI by blowing up a small image will cause it to appear blurry on screen.

The word pixel stands for picture element. Each digital image contains pixels that hold the colour information that make up the whole picture. If you zoom far enough into an image on a screen, you will see the pixels of that image.

DPI stands for dots per inch and only refers to the density of the dots that is used by the printer when printing an image.

Bioanalytical and medical applications isolate wavelengths with bandpass filters to detect biomolecules and cellular structures.

Resolution refers to the number of pixels in an image. Resolution is usually identified by the width and height of the image as well as the total number of pixels in the image.

For example, if you increase the size of your image by 300%, the print on the paper will become three times as large, but it will result in a more rough-looking or blurry image.

In spectroscopy, spectral lines are analyzed by selectively blocking or transmitting certain wavelengths using bandpass filters.

Our bandpass filters are designed to transmit a precisely defined range of wavelengths, making them ideal for a wide range of applications such as spectroscopy or bioanalysis.

We demand the highest standards of materials and manufacturing processes to ensure excellent image quality, starting with the production of the optics. Our standards go beyond the production of individual components. We master the entire production process from raw glass to finished filters and are able to process all common types of glass. Our special coating technologies give the optics or lenses the desired optical properties.

Our industrial optical bandpass filters are tested to DIN standards to ensure they meet stringent environmental requirements. These tests check the durability of the bandpass filters, their resistance to temperature changes and their ability to withstand exposure to harsh chemicals and other environmental stressors. This ensures that the bandpass filters are up to the task in demanding industrial applications, providing consistent performance and reliability over time.
