λ 拉姆达（20-25）袖珍系列双筒望远镜产品采用了双铰链结构设计，以实现体积小巧，重量轻盈的需求。镜体采用镁合金材质，确保其稳定性和轻便性。配备超低色散镜片，有效减少图像的色差和色散现象，呈现更加真实和清晰的观测图像。BAK4材质棱镜使产品体积紧凑，便于携带和操作。屋脊棱镜镀有相位膜，提高成像的清晰度和细节呈现。透镜和半五棱镜采用了先进的镀膜技术，透过率达到94%，使观测图像更加明亮。另外，产品采用了IPX7防水设计和氩气填充，确保在各种复杂环境下正常工作。无论您是观鸟、寻蜂，还是观星、户外探险爱好者，它都能满足您对清晰、明亮、舒适观测的需求。
Extra-low Dispersion Glass: ED lens (Extra-low dispersion glass) for chromatic aberration compensation and brighter, clearer viewing.
Phase Coating: Phase Coating of roof prism for color reproduction and high resolution.
Super Fully Multi Coating: Super Fully Multi Coating is applied to transmission surfaces of all lenses. The image by SMC is clearer and brighter than FMC.
Magnesium Alloy: Magnesium Alloy body chassis makes the products to be durable, stable, falling resistance and used in the situation with obvious temperature variation.
Bak4 Material: BAK4 has higher light reflection than BK7. It can effectively shorten the optical path and make the structure of optical products more compact.
Argon Filled: Argon Filled is batter than Nitrogen Filled and has a lower thermal conductivity. It can effectively resist oxidation, corrosion and fogproof.
Pocket: Compact and small, light weight. Easy to carry and put into pocket.
High Reflection Dielectric Coating: High Reflection Dielectric Coating is a coating with high reflectivity, which can transmit lights with less loss than silver and aluminum coating to obtain higher transmittance.
Ultra High Definition: UHD (Ultra High Definition) optical system captures more image details.
ShuntuCare: It doesn't matter how it happened, whose fault it was. If you ever have a problem, no matter the cause, we promise to take care of you.
IPX7: Ingress of water in quantities causing
harmful effects shall not be possible
when the enclosure is temporarily
immersed in water under standardized
conditions of pressure and time.
