Fixed Focal Length Lenses
Fixed focal length lenses have large maximum apertures, enabling high performance even in low light conditions. At Shanghai Optics we manufacture high quality fixed focal length lenses that provide sharp, clear imagery in high resolution, depth of field, and with minimal optical distortion. The quality construction that characterizes each of our imaging lenses ensures they will perform consistently over a wide range of conditions, and they are appropriate for use in industry, research, and security applications. Our extensive selection includes a full range of fixed focal lenses of 2/3”, 1”, and 4/3” sensor formats, and a special high resolution range optimized for 43.4mm sensor format. Each of our lenses have a focusing range from 1 meter or less to infinity, and certain of our fixed focal length lenses are designed to focus from a working distance of as short as 50 mm. They are designed to provide clear imagery from the center to the corner of the field. Our lenses can be used with either CCD or CMOS cameras.

Applications of Fixed Focal Length Lenses
Fixed focal length lenses are the optical eyes of robotic vision systems, and industrial machine vision lenses have important applications in quality control as well as in measurement systems, process control, and robot guidance. Fixed focal length lenses are commonly used in machine vision applications. Consistent, reliable performance is a basic requirement of industrial machine vision lenses.
In research and medical imaging, machine vision lenses are playing an increasingly vital role. Fixed focal length lenses have opened up new horizons in medical diagnostics, providing detailed images of areas beyond the reach of the human eye and enabling computerized analysis of potential issues. In research, computer vision facilitates the collection and analysis of vast amounts of data, expanding the boundaries of human knowledge. The use of multiple machine vision systems, each with unique optical constraints and capabilities, provides diverse perspectives on a given situation.
Fixed focal length lenses are also essential in surveillance systems, ranging from high-resolution monitoring of large areas to basic coverage of retail spaces. In defense, space exploration, and conservation, machine vision has become indispensable for numerous applications.
For precision imaging and scientific research, high-quality objectives are needed to produce high-resolution images with low distortion and high contrast. The intermediate image is the image formed by the objective lens before it reaches the eyepiece or camera, and it should be clear and well-resolved for accurate analysis. The refractive index of the medium between the objective and object is critical in determining the working numerical aperture and also the resolution of a microscope objective. Objective numerical aperture can be dramatically increased by designing the objective to be used with an immersion medium, such as oil and water.
Shanghai Optics offers many types of pre-engineered objectives including plan achromatic objectives, plan fluorite objectives, plan apochromatic objectives, and super apochromatic objectives for a wide range of applications. In many cases, custom microscope objectives are the best option for special applications.
