Theia Technologies提供了许多百万像素镜头，包括使用Linear OpticalTechnology®的远摄镜头和超宽非畸变镜头。

Theia 4K分辨率镜头和4K相机兼容镜头支持新的最高分辨率相机。这些镜头设计用于1 / 2.3“，1 / 1.7”和最大2/3“图像传感器。

超广角镜头使用Theia的专利线性光学技术®来校正镜头的镜筒畸变，而无需其他软件来使图像变形。这些镜头可提供高达135°的水平视场而不会发生镜筒变形。

中焦距镜头的视场范围不太宽，远摄镜头也不太适合。

Theia远摄镜头具有长焦距和长焦距，但体积小巧，适合在小型外壳中使用。它们经过昼/夜校正，可用于红外照明。

Theia电动镜头包括用于遥控对焦和变焦的马达，红外截止模块以及用于对焦和变焦的限位开关。这些紧凑型镜头专为4K分辨率球型和子弹型摄像机而设计。

Theia鱼眼镜头设计用于360相机，因此它们将呈现必须在相机或服务器中变形的完整圆形图像。这些镜头专为在房间中央安装一台摄像机的应用而设计。

Theia机器视觉镜头与安全镜头在光学上相同，但可提供C卡口。

Theia的某些镜头提供了电机控制器，翼形螺钉更换套件和滤镜安装座等配件。

Theia的图像分辨率模拟器和镜头计算器

Theia的镜头计算器（更准确地说是图像分辨率计算器）使您可以看到不同镜头-相机组合的期望。图片代表给定相机镜头组合的视场和图像分辨率。您可以使用这些图片来为您的客户设定一个期望，即可以读取多远的车牌或可以看到人的面部细节水平。

计算器会显示一张图片，该图片表示您可以从相机和镜头组合中获得的图像分辨率，以及一张显示视野范围的图片。

应用领域

Theia的镜头可用于从安全性到机器视觉，科学到网络摄像头的许多不同应用。这里只是几个例子

-入口门和大厅，用于安全和监控
-小房间和牢房
-学校和大学等公共场所
-关键基础设施，例如电站和化工厂
-仓库和大型零售店
-警察和教养设施
-边界和周边安全
-科学和网络摄像头
-从传送带上的巧克力到太阳能电池板检查的机器视觉应用

Theia Technologies offers many megapixel lenses including telephoto and ultra wide non-distorted lenses using Linear Optical Technology®.  

4K resolution lenses and 4K camera compatible lenses support the new highest resolution cameras.  These lenses are designed for use with 1/2.3", 1/1.7", and up to 2/3” image sensors.  

Ultra wide angle lenses use Theia's patented Linear Optical Technology® to correct barrel distortion in the lens without the need for additional software to dewarp the image.  These lenses can provide horizontal field of view up to 135° without barrel distortion.  

Mid focal range lenses fit the bulk of security and machine vision applications with their not-too-wide not-too-telephoto field of view.  

Telephoto lenses offer a long focal length and long reach but are compact for use in small enclosures.  They are day/night corrected for use with IR illumination.  

Motorized lenses include motors for remote focus and zoom, IR cut module, and limit switches for focus and zoom.  These compact lenses are designed for 4K resolution dome and bullet style cameras.  

Fisheye lenses are deigned for 360 cameras so they will present a full circular image that must be dewarped in the camera or server.  These lenses are designed for applications where one camera in the center of the room is appropriate.  

Machine vision lenses are optically the same as their security lens counterparts but are available with C-mount.  

Accessories such as motor controllers, thumbscrew replacement kits, and filter mounts are available for some of Theia’s lenses.  

Theia's image resolution simulator and lens calculator

Theia's lens calculators (more accurately image resolution calculators) let you see what to expect from different lens-camera combinations. The pictures represent the field of view for a given camera-lens combination and the image resolution. You can use these pictures to set expectations for your customer about how far away a license plate can be read or what level of detail can be seen in a person's face.

The calculator show a picture that represents the image resolution you can expect from the camera and lens combination as well as a picture showing how wide the field of view is. 

Applications

Theia's lenses can be used in many diverse applications from security to machine vision to science to web cams.  Here are just a few examples of

- Entry doors and lobbies for security and monitoring
- Small rooms and holding cells
- Public spaces such as schools and universities
- Critical infrastructure like power stations and chemical plants
- Warehouse and big box retail stores
- Police and correctional facilities
- Border and perimeter security
- Science and web cams
- Machine vision applications from chocolates on a conveyor belt to solar panel inspection
