引燈鏡頭應(yīng)用:深圳工業(yè)燈鏡投影機(jī):投影機(jī)主要由凸透鏡成像制成,可以放大,倒立實(shí)體圖像原理。在投影中,從投影膜到凸透鏡成像的距離保持在焦距的12倍之間,然后借助平面鏡更改光的折射定律方位。凸透鏡成像越靠近投影膜,圖像越大,反向越小。投影時(shí),首先將投影膜放在載波表上,然后調(diào)整投影膜到凸透鏡成像的距離,并注意調(diào)整平面鏡的角度,使圖像在螢?zāi)恢虚g。放大鏡:在1f中,物體處于正位置,放大正位置的虛擬影像,放大正位置的虛擬影像,放大虛擬影像。使圖像更大,使物體遠(yuǎn)離鏡頭(接近1f)。如果你想要帶放大鏡的指紋,如果你想要一個(gè)指紋來回答,當(dāng)你不動(dòng)的時(shí)候,把放大鏡從手指上移開。手指接近1f。
集成化控制模組鏡片的結(jié)構(gòu)分析對于高端鏡片來說是非常重要的,但如何將一個(gè)好的光學(xué)設(shè)計(jì)轉(zhuǎn)換成一個(gè)商品則是最重要的。然而,鏡片(特別是高端光學(xué)鏡片)是如何制作、組裝和檢測的?本文以中倍鏡為例,簡要介紹了該鏡片的電子光學(xué)冷拉、結(jié)構(gòu)設(shè)計(jì)和裝配工藝。
很多沒有電子光學(xué)冷拉生產(chǎn)車間的好朋友對集成化控制模組鏡片的生產(chǎn)加工技術(shù)性都很好奇,事實(shí)上,電子光學(xué)冷拉就是分割、精拋、精拋、打磨拋光、邊磨、鍍層、膠水粘等。具體的電子光學(xué)冷拉技術(shù)性在這里并不詳細(xì),這里是國內(nèi)光學(xué)鏡頭一般加工精度的重點(diǎn)。以便保持商品的品質(zhì),大家必須對商品開展檢測,對光電材料商品的外觀檢測列出一些相關(guān)問題。點(diǎn)缺陷:由于點(diǎn)形缺陷,檢測人員應(yīng)以最大直徑測量其尺寸。如顏色點(diǎn)的出現(xiàn)、氣泡、凹坑、油漬等不良現(xiàn)象。毛邊:由于精密模具預(yù)成型零件參數(shù)或模具,會(huì)使商品的邊沿或分型面產(chǎn)生廢緣。粗糙邊沿主要是胚胎擠壓后磨削不均造成的。硬刮痕:由于硬材料磨損,商品表面有深刻的刮痕。大多數(shù)都是機(jī)械的。劃痕:沒有深刻劃痕。一般在分揀中,包裝過程不符合標(biāo)準(zhǔn)操作,追蹤不易找到。
Applications of Projection Lenses: Shenzhen Industrial Projection Lamps
Projection lamps primarily use convex lenses to create magnified and inverted real images.
Projection Principle
? The distance between the projection film and the convex lens must remain within 1 to 2 times the focal length.
? Plane mirrors are used to adjust the light’s direction according to the law of refraction.
? The closer the convex lens is to the projection film, the larger the image becomes, and the inversion effect decreases.
Steps for Projection
1. Place the projection film on the carrier table.
2. Adjust the distance between the film and the convex lens.
3. Modify the angle of the plane mirror to ensure the image appears centered on the screen.

Magnifying Glass Applications
? At a distance of 1f, the object is in an upright position, and the magnifying glass produces a virtual, upright, and magnified image.
? Moving the object closer to the lens (near 1f) enlarges the image.
Example:
To examine a fingerprint using a magnifying glass:
? Adjust the lens’s distance from the fingerprint for a clear image.
? To enlarge further, move the lens closer to 1f and the object.

Structural Analysis of Integrated Control Module Lenses
High-end lenses require converting optical designs into practical products through meticulous manufacturing and assembly processes.
Example: Medium Magnification Lens
The production process includes:
? Optical Cold Drawing techniques such as:
o Cutting
o Precision grinding
o Fine polishing
o Edge grinding
o Coating application
o Adhesive bonding
Although details of optical cold drawing processes are not fully described, this method is crucial for achieving precision in lens manufacturing.

Quality Inspection for Optoelectronic Materials
To maintain product quality, optical materials undergo appearance inspections.
Common Defects:
1. Point Defects:
o Inspectors measure the maximum diameter of defects like color spots, bubbles, pits, or oil stains.
2. Burrs:
o Caused by pre-molding parameters or mold issues, resulting in waste edges at the product’s perimeter or parting line.
o Rough edges are often caused by uneven grinding after preform extrusion.
3. Hard Scratches:
o Deep scratches caused by abrasion from hard materials, typically during mechanical processing.
4. Surface Scratches:
o Shallow, superficial scratches often occur during non-standard sorting or packaging processes, making them harder to trace.
By addressing these issues during manufacturing and inspection, optical lenses achieve the precision and quality necessary for advanced applications.
