Cylindrical Lenses
Mok Optics specializes in manufacturing high-quality optical components, including aspherical lenses, aspherical cylindrical lenses, and cylindrical lenses. These advanced optical elements are designed to combine the aberration-reducing capabilities of aspheric surfaces with the one-dimensional focusing properties of cylindrical lenses. Their primary function is to correct optical aberrations while providing precise, targeted control of light in a single dimension. This makes them indispensable in a wide range of applications, from laser optics to imaging systems.
Aspherical and Cylindrical Lenses: Key Features
- Aspherical Lenses: These lenses reduce spherical aberrations by employing surfaces that are not part of a sphere, leading to improved image quality and optical performance.
- Cylindrical Lenses: Unlike spherical lenses that focus light symmetrically in two dimensions, cylindrical lenses focus light in only one dimension. This characteristic allows cylindrical lenses to provide magnification along a single axis.
- Aspherical Cylindrical Lenses: These lenses merge the aberration-correcting qualities of aspheric lenses with the linear focusing capability of cylindrical lenses, offering superior control over optical performance.
Applications of Cylindrical and Aspherical Cylindrical Lenses
Mok Optics’ positive cylindrical lenses are highly versatile and can be tailored for specific industrial and scientific applications:
Anamorphic Beam Shaping
Cylindrical lenses are frequently employed in anamorphic optical setups where two lenses are used to reshape laser beams. By using two cylindrical lenses at varying orientations, the beam’s profile can be adjusted to fit specific output requirements.Laser Diode Collimation
Laser diodes typically emit elliptical beams, which require collimation and reshaping for efficient use in various optical systems. A pair of positive cylindrical lenses can be used to circularize and collimate the output beam from a laser diode, optimizing it for a range of laser applications.Beam Focusing
In certain applications, such as sensor systems, a single cylindrical lens is used to focus a diverging beam onto a detector array. This is essential in systems that need to focus light along one axis while allowing it to remain unaltered along the perpendicular axis.
Materials Used in Mok Optics’ Cylindrical and Aspherical Lenses
Mok Optics uses a wide array of high-quality materials to manufacture lenses optimized for specific wavelength ranges, from ultraviolet (UV) to infrared (IR). The choice of material directly affects the lens’ transmission properties, durability, and performance across different wavelengths.
1. Optical Glass
Mok Optics utilizes premium optical glasses from well-known brands such as CDGM, SCHOTT, OHARA, and HOYA. These materials are chosen for their clarity, low dispersion, and high transmission in visible and near-infrared wavelengths.
2. UV-Grade Fused Silica
For applications that require high transmission in the ultraviolet range, Mok Optics offers lenses made from UV-grade fused silica. Common materials include:
- JGS1
- Corning 7980
These types of fused silica provide excellent transmission at UV wavelengths and are ideal for UV laser systems and imaging applications.
3. IR-Grade Fused Silica
For infrared applications, Mok Optics uses IR-grade fused silica materials such as:
- JGS3
- Corning 7979
These materials exhibit superior performance in the infrared spectrum, making them suitable for IR-based systems, including thermal imaging and laser optics.
4. IR Crystals
To meet the specific needs of infrared optical systems, Mok Optics offers a range of lenses manufactured from IR-grade crystals. These include:
- Germanium: Commonly used for thermal imaging due to its excellent IR transmission.
- Sapphire: Offers high durability and scratch resistance, along with excellent transmission in the infrared.
- Magnesium Fluoride (MgF2) and Calcium Fluoride (CaF2): Known for their high transmission in both UV and IR ranges.
- Zinc Selenide (ZnSe) and Zinc Sulfide (ZnS): Ideal for CO2 laser optics and other IR applications.
Material Selection for Specific Wavelengths
Each material offers specific advantages based on the wavelength range required for the application. For example:
- UV-Grade Materials: Best suited for applications below 400 nm, such as UV lasers.
- IR-Grade Materials: Ideal for wavelengths beyond 700 nm, commonly used in thermal imaging and infrared laser systems.
