Autofocus performance often defines how well a lens integrates into modern workflows, and AstrHori’s use of an STM (stepping motor) combined with a leading screw mechanism promises to offer a smooth, silent operation. This makes the lens more appealing for video creators, as silent focusing prevents mechanical noise from disrupting audio, and the internal focus mechanism enhances durability by protecting against dust and debris. Its internal focus should maintain consistent lens length, a feature appreciated by filmmakers using stabilizers or gimbals.

According to the homogenization principle, a laser beam passes through each individual microlens, effectively homogenizing the beam and resulting in a uniform and consistent output. This uniformity ensures more precise and reliable optical performance, making them particularly beneficial in various applications.

In a digital projector, microlens arrays can be used to focus light on to the active area of the LCD to generate the image which will be projected. A novel design for a LED pico-projector involves using a special array of 45 microlenses aligned on the display coverglass.  The use of a microlens array in this projector design allows the projector to be highly compact and  robust while still being capable of producing bright, crisp imagery.

When a pair of fly’s eye arrays is used in combination with a condenser lens they can provide uniform irradiance at the illumination plane.  When set up in this configuration the first array is called the objective array, and the second the field array.

The AstrHori AF 27mm f/2.8 is available to preorder now in Nikon Z mount for $126. The lens is also available to order from Pergear. E and X-mount versions of the lens are also expected to arrive soon, but are not yet available for purchase.

The 27mm focal length, equivalent to approximately 40mm on a full-frame sensor, strikes a balance between wide-angle and standard perspectives. This field of view closely matches the natural human perspective, making it an intuitive choice for a variety of genres. Street photographers will appreciate its ability to capture candid scenes with context, while portrait photographers will enjoy the subtle compression and natural framing it offers. Landscape shooters will find the focal length wide enough to encompass sweeping vistas without falling into distortion.

A fly’s eye array consists of individual square or rectangular microlenses mounted on a substrate in a close-packed, no-gaps configuration. A typical array will have 7-11 channels in each direction, optically overlapped in the illumination plane.  The surface of the microlenses may be either anamorphic or spherical.

AstrHori has built its reputation on creating lenses that prioritize usability. Known for manual prime lenses, the brand has found favor with enthusiasts looking for a no-frills design. With the AF 27mm f/2.8, AstrHori ventures further into autofocus technology while retaining its emphasis on delivering exceptional value.

Microstructure lens arrays excel in achieving a harmonized balance of customization and diversity, setting them apart from conventional optical components. Their unique ability to cater to specific customer requirements for beam patterns makes them indispensable in the field of optics. Beyond their fundamental functionalities of focusing and imaging, their small sub-lens sizes and high integration enable them to achieve effects unattainable by traditional optical elements. This pivotal characteristic has rendered them essential components in cutting-edge optical systems, playing a crucial role in the advancement of optical technology.

AstrHori’s AF 27mm f/2.8 lens enters the autofocus market with quiet confidence, promising an affordable and portable option for creators on-the-go.

Microlens arrays offer large field of view angles, high temporal resolution, low aberration and distortion, and infinite depth of field, making them ideal for 3D imaging and other optical applications requiring non-Gaussian uniformity and high efficiency. For instance, in digital projectors, microlens arrays focus light onto the LCD’s active area to generate bright, crisp images. We’ve developed a novel LED pico-projector design incorporating a special array of 45 microlenses aligned on the display cover glass, resulting in a highly compact yet robust projector.

Square microlens arrays are primarily used for beam homogenization and shaping. Their very high fill factor (up to 98%) essentially eliminates zero order hot spots in the illuminated field. A standard square microlens is 10mm x 10mm configuration, although we can provide custom sizes upon request.  A variety of focal length and lens pitch options are also available.

Microlens arrays are rigid arrangements of very tiny lenses, each with a diameter of less than 10 millimeters. These arrays may be one or two dimensional, and are mounted in a regular pattern on a supporting substrate. The microlenses themselves may be circular, square, or hexagonal, and the array may be square, hexagonal, or some other geometric shape.  Microlens arrays are used in optical microscopes and light fields cameras, on CCD arrays, and for 3D imaging and displays, fiber coupling, optical sensors and LIDAR systems.

At Shanghai Optics, we produce both 1- and 2-dimensional arrays in various configurations, sizes, and focal lengths. These arrays are manufactured from high-quality fused silica, ensuring optimal performance ranging from 193 nm to 2.5 micrometers. The index of refraction of these arrays is 1.561 at 248 nm and 1.444 at 1550 nm.

At its core, the lens features a six-element, five-group optical design. However, its six-blade aperture won’t produce perfectly round bokeh. The aperture ranges from f/2.8 to f/16, offering flexibility for shallow depth of field or sharp focus across the frame. It also boasts a minimum focusing distance of 12 inches (30 centimeters).
