Plano-Convex
Lenses
This kind of lens has positive focal lengths. They work
best when producing real images at near infinite conjugates
or where one of the conjugates is virtual. ........
|
|
| |
| |
| |
| |
 |
Equi-Convex
Glass Lenses
These lenses have large range of lengths and are the optimum
shape for producing real images at 1:1 magnification.

| |
 |
Plano-Concave
Glass Lenses
There popular applications are to increase focal lengths
in existing systems. They are a more suitable choice than
the equivalent equi-concave ........ |

Equi-Concave
Glass Lenses
The equi-concave lens has a focal length, diverges collimated
incident light, and forms only virtual images that are
seen through the lens......... |

Meniscus
Glass Lense
If these lenses are used in combination with other
components, it is possible the focal length of the assembly,
without significantly increasing the axial aberrations.

Micro
Lenses
These lenses are very small, and their diameter varies
from 1.5mm to 4mm. They are made of precise components

Ball
Lenses
We put out these ball lenses from optical glasses to provide
a high coupling efficiency when used with fiber optics.........

Achromatic
Doubles
These lenses include two different lasses. They are crown
and flint. There are three specific wavelength bands available.......

Fused
silica and Fused Quartz Lenses
Like the glass lenses previously described, they have
a negative focal length and are often used to expand beams
or to increase focal length........ |

Cylindrical
Lenses
Cylindrical lenses are either plano-convex or plano-concave
in form and rectangular in shape ........ |

Sapphire
Lenses
Sapphire is an excellent optical material. It has a
very broad transmission range extending from 0.15 to
6.0 um. ........ |

Cone
Lense
Cone Lenses can be used for 360 illumination and imaging
applications. Provided in coated and uncoated versions
to allow special user-applied coatings if desired. ........

Micro
Half-Ball Lenses
Half-ball (hemispherical) lenses are ideal for applications
such as fiber communication, endoscopy, microscopy,
optical pick-up devices, and laser measurement systems.

Rod
Lenses
Rod Lenses are polished on the circumference and ground
on both ends. Optical performance is similar to a cylinder
lens. ........ |
|
| |
|
| |
| |
| |

Diffraction
Limited Large Achromats
High quality lenses are color-corrected and free of spherical
aberrations to less than 1/4 wavefront error. ........
|
|
| |

Negative
Achromatic Lenses
Consisting of two optical elements cemented together,
negative achromats are corrected for color and on-axis
aberrations. ........ |
|
