In the design of optical systems, there are significant differences in the requirements for lens size and installation space in different apps. CoreMorrow N81KxxTxx piezo screw optical mount, with a resolution at the sub-micro arc level, is compatible with lenses ranging from 25.4mm to 116mm in diameter and is widely used in scenarios such as laser cavity adjustment and beam directivity regulation.
With the popularization of micro optical devices and embedded modules, the application demand for "space-constrained + small-sized lenses" is increasing day by day. For this reason, based on the N81A compact piezo screw actuators, CoreMorrow has developed the N81AK8T13 piezo optical mount that is compatible with 12.7mm (0.5-inch) lenses, which can not only meet the requirements of high-precision piezoelectric adjustment, It can also be embedded in a compact structure, specifically addressing the precise adjustment requirements of small-space and low-load scenarios.
I. Core Configuration and Technical Characteristics of N81AK8T13 Piezo Screw Optical Mount
1. Core Drive: N81A Compact Piezo Screw Actuator
The N81A compact piezo screw actuators inherit the core technical advantages of N81 and have been precisely adapted to the miniaturization requirements.
▲Resolution: Maintaining nanometer-level displacement resolution to meet more precise positioning requirements;
▲Small Size: Precisely matched with the demand for smaller-sized 12.7mm optical lenses;
▲Structural Design: The volume has been further optimized, and the compact layout is suitable for narrow installation Spaces.
▲Core Functions: Classic features such as touch-free adjustment, self-locking at rest, and long-term stability.

2. Lens Mount: Custom Standard Size of 12.7mm
Compatible Specifications: Specifically designed for 12.7mm diameter lenses, compatible with commonly used small-aperture optical components in the industry (such as miniature mirrors, small-sized lenses, etc.);
Structural Optimization: The frame adopts a lightweight design and an integrated compact structure, reducing the overall occupied space while ensuring the stability of lens installation.

Both the N81KxxTxx series piezo optical mounts and the N81AK8T13 support touch-free adjustment and self-locking at rest. The core difference lies in the optimization of "load-size" scene adaptation designed for different demand scenarios.
II.Core Application Scenarios of Piezo Screw Optical Mount
N81AK8T13 piezo optical mount is not merely a reduction in size, but a precise fit based on the requirements of the scene:
1. Compatible with lightweight lenses to meet the actual load requirements of small lenses;
2. Balance accuracy and miniaturization, meeting the sub-micro arc adjustment requirements of most scenarios;
3. The adaptation of the 3.12.7mm standard lens size enhances the efficiency of system integration.
Due to the design of the N81AK8T13 piezo optical mount concentrated on small spaces and small-sized lenses, precise matching can be achieved in the following scenarios:
▲Micro optical instruments: portable interferometers, micro microscopes, handheld laser measurement devices, etc. The compact structure is suitable for the miniaturized design of the instruments, and the high resolution ensures measurement accuracy.
▲Embedded optical modules: micro-modules for optical communication, core components of small liDAR, etc., enabling precise adjustment of beam orientation and incident/exit angles in confined Spaces.
▲ Small-aperture optical path adjustment:Small laser cavities, micro-nano optical experimental devices, etc. The miniaturized design makes it easy to embed and allows for touch-free adjustment.
The new product N81AK8T13, together with the N81KxxTxx series, forms a product layout covering both large and small sizes, providing targeted piezoelectric regulation solutions for different optical systems. CoreMorrow will continue to optimize the compatibility design of piezo actuators and mounts based on application requirements, and promote the application of high-precision 9 optical adjustment technology in more specialized fields.
