Different types of Optical Filter
Light is an essential component of life. It is used in the process of photosynthesis that creates the food that we ate. It also illuminates our home so we can live conveniently. And most fascinatedly, light is applied to both scientific and industrial setting and is being used in wide variety of tools. In the field of photography, light also plays a significant role. This is now when optical filters come into the picture. It represents one of the essential elements used in changing the light properties. Through the use of glass or plastic as a substrate, setting up thin films of materials that affect the light makes optical filters. Basically, it determines how much light is transmitted, absorbed, reflected and its polarization. Optical filters have been a key element in the realm of photography. While some components have changed over time due to the continuous advancement of technology like Fluorophores and optical filters in Microscopy, the function and essence of optical filters did not change at all. So if you are a photographer and not yet sure what filter best suits your needs, you are in the right place. This article will go through some of the best types of optical filters that you may want to consider.
Bandpass Filters
One of the most popular types of optical filters is the bandpass filter. This type of filters allows only particular wavelength band to pass through the lens. One of the amazing things about Bandpass is that it is now being applied to the realm of astronomy. Bandpass filters belong to the group of modern interference filters that have central wavelength to address particular requirements in photometry, spectroscopy, laser separation and clinical chemistry.
Laser Line Filters
Basically, this type of filters eliminate unfavorable radiation. This type of filter is also being used to help medical professionals engineers and even scientist to enable fiber-optic communications, surgical operations and even sequence DNA. The main purpose of laser line filters is to emit radiation that is not monochromatic in nature.
Color Temperature Correction Filters
If you are looking for an optical filter that has the ability to capture precise integrity in photographic, then color temperature correction filters are the right one for you. This type of filter is being used in medical, stage lightning and industrial setting. It has also the ability to control light wavelength transmission and reflection, as needed for the accurate appearance of even the most esoteric color blends.
Color Temperature Correction
When capturing photos, the color integrity of the subject must always be given importance. In stage lighting, photographic and even in industrial applications, color temperature correction filters have been very helpful and useful. This type of filter controls the transmission of wavelength and the needed reflection in order to have precise appearance. With the 650 degree coatings, this type of filter is also suitable for high intensity lighting.
Dichroic Filters
Another type of filter that you may want to consider is the dichroic filter. It has the ability to give emphasis on the retail displays and theatrical light shows. It also upholds the value of color separation that gives means to project and control specific colors brightly and efficiently.
Basic Filters
But if you don’t want to buy a lot of filters for your endeavor, there are basic filters that you can choose and you will certainly not go wrong with them. The most basic filters are protection filters and ultra-violet reducing filters. These filters are considered to be classic and it can be used in wide variety of aspects of photography. UV filters are considered as Haze filters. They are designed to cut through the effects of haze atmosphere. They can also be used to act as prevention for any other forms of pollutants that may contribute to the degradation of the image. Haze filters are also available in different strengths so you’ll have a lot of options depending on your need and preference.
Overall, optical filters come in variety of types. Each type has its own functions and uses. Knowing these filters will allow you to use the right element that will contribute to the overall appearance of the image you are working on.
