Optics has a vital role in a variety of engineering applications, and the 39-04-3A is a versatile addition to this technology. It is an adjustable lens that is used to control light passing through a specific area, which is typically used in laser applications, photography, and projection systems.

This lens consists of two optical components; an adjustable Lens Barrel, or Lens Cell, and an Attenuator Plate. The Lens Barrel is made up of a number of closely stacked lenses, from six to sixty-four. The lenses are separated at regular intervals by baffles, which control the size and shape of the beam by varying its incidence angle. The Adjustable Lens Barrel allows for a wide range of Lens Cell sizes and shapes, which allows for better control of light distribution. The Attenuator Plate is a metal sheet coated with insulating material, which modulates the light passing through the Lens Barrel.

The working principles of the 39-04-3A lens are based mainly on two phenomena; refraction and diffraction. When a beam of light enters the Lens Barrel, the baffles and lens elements bend and focus the light, resulting in a narrow, focused beam of light exiting the other side. The Attenuator Plate also affects the light beam’s intensity and wavelength. The combination of these two forces allows for precise control of light distribution and intensity.

One of the most commonly used applications for the 39-04-3A is for laser applications. This lens can be used to control and shape the beam for use in laser cutting and marking, as well as for laser welding. It can also be used to create a polarized laser beam, which is useful for high security applications such as access control and authentication systems. This lens is also commonly used in photography and projection systems, where its adjustable lens and attenuator plate help to create an even, focused light beam.

The 39-04-3A lens is a versatile and powerful tool for controlling light. Its adjustable lens and attenuator plate allow for a wide range of applications, from laser applications to photography and projection systems. With its precise control and wide range of applications, the 39-04-3A lens is a reliable and essential component of any Optical system.
