我们的光学晶体主要分为以下几类：

Our optical crystals are mainly divided into the following categories:

• 非线性晶体：用于频率转换、参量振荡、倍频等应用
• Nonlinear crystals: Used for frequency conversion, parametric oscillation, frequency doubling and other applications
• 激光晶体：适用于各种固体激光器，如Nd:YAG、Yb:YAG等
• Laser crystals: Suitable for various solid-state lasers, such as Nd:YAG, Yb:YAG, etc.
• 双折射晶体：用于制造波片、偏振棱镜等偏振光学元件
• Birefringent crystals: Used to manufacture wave plates, polarizing prisms and other polarization optical components
• 声光晶体：应用于调制器、偏转器等声光器件
• Acousto-optic crystals: Applied to acousto-optic devices such as modulators and deflectors

这些晶体广泛应用于激光加工、医疗设备、科研仪器、通信系统等领域。

These crystals are widely used in laser processing, medical equipment, scientific research instruments, communication systems and other fields.

选择光学镜头时需要考虑以下几个关键因素：

When selecting optical lenses, the following key factors need to be considered:

• 焦距：根据成像距离和视场角要求选择
• Focal length: Selected based on imaging distance and field of view requirements
• 光圈：影响进光量和景深
• Aperture: Affects the amount of light entering and depth of field
• 分辨率：根据检测精度要求确定
• Resolution: Determined based on detection accuracy requirements
• 工作波段：确保镜头在所需光谱范围内有良好透过率
• Working wavelength: Ensure the lens has good transmittance in the required spectral range
• 接口类型：与相机接口匹配
• Interface type: Matches the camera interface

光学元件的清洁和维护需要特别注意：

Special attention is required for cleaning and maintenance of optical components:

• 使用专用的光学清洁工具，如吹气球、光学棉签、无尘布
• Use special optical cleaning tools, such as air blowers, optical cotton swabs, and lint-free cloths
• 按照正确的清洁顺序：先吹气除尘，再用溶剂清洁
• Follow the correct cleaning sequence: first blow off dust with air, then clean with solvent
• 使用高纯度溶剂，如无水乙醇、丙酮（注意材料兼容性）
• Use high-purity solvents, such as absolute ethanol, acetone (pay attention to material compatibility)
• 避免用手直接触摸光学表面
• Avoid touching optical surfaces directly with hands
• 存储在恒温恒湿环境中，避免温度剧烈变化
• Store in a constant temperature and humidity environment, avoid drastic temperature changes
