Description

The Seiler Objective Lens is designed for use with the Alpha Air and Alpha Slim dental/ENT microscopes, as well as the colposcope models 935, 955, and 985. The operating scopes generally come with a standard objective, but the different lengths are all interchangeable.

250 mm (50 mm = 2") gives about 10" of working distance (300 mm = 12", 350 mm = 14", etc.).

The versatile Objective Lens is also compatible with previous models, such as the Evolution xR6 and IQ dental/ENT microscopes.

Frequently asked questions

Are the Seiler objective lenses fully interchangeable?

Yes, the Seiler Objective Lenses are designed for full interchangeability. This is a core selling point that allows users to easily swap components to achieve the desired working distance for specific procedures.

These objectives are compatible with Seiler Alpha Air, Alpha Slim, and various colposcope models. You can choose from the following interchangeable focal lengths:

  • 175 mm
  • 200 mm
  • 250 mm (Provides a working distance of approximately 10 inches)
  • 300 mm
  • 400 mm
What is included with the Objective Lens purchase?

When you purchase the Seiler Objective Lens, you receive the complete unit, which is supplied as Factory New.

The purchase includes:

  • The Objective Lens Unit (specific to the focal length you select, ranging from 175 mm to 400 mm).
  • The Locking Mechanism/Adjustment Knob (which is integrated into the unit for secure attachment to your microscope).
Is this objective lens factory new?

Yes, the Seiler Objective Lens is guaranteed to be Factory New.

As a crucial optical accessory for enhancing the functionality of Seiler surgical microscopes and colposcopes, its new condition ensures the highest level of precision and reliability for critical medical procedures.

What Seiler microscopes is the lens compatible with?

The Seiler Objective Lens offers wide compatibility across several Seiler dental, ENT, and gynecological platforms, allowing you to easily customize the working distance for various procedures.

This interchangeable objective lens is designed for use with:

  • Dental and ENT Microscopes: Alpha Air, Alpha Slim, Evolution xR6, and IQ models.
  • Colposcopes: Seiler models 935, 955, and 985.

This interchangeability allows you to achieve the optimal working distance for your procedure, with focal length options ranging from 175 mm up to 400 mm. For instance, the 250 mm length provides approximately 10 inches of working distance.

What is the working distance of the 250 mm lens?

The 250 mm Seiler Objective Lens provides a working distance of approximately 10 inches.

This length is fully interchangeable with other available focal lengths, including 175 mm, 200 mm, 300 mm (which provides approximately 12 inches), and 400 mm. This customization ensures clinicians can achieve the precise working distance required for procedures across dental, ENT, and colposcopy applications.

What interchangeable focal lengths are available?

The Seiler Objective Lens is available in five interchangeable focal lengths, which are designed to precisely adjust the working distance of your compatible microscope (Alpha Air, Alpha Slim, or Colposcope models).

Available options include:

  • 175 mm
  • 200 mm
  • 250 mm (Provides approximately 10 inches of working distance)
  • 300 mm (Provides approximately 12 inches of working distance)
  • 400 mm

These interchangeable lenses allow for customization based on the required access and illumination geometry of specific clinical procedures.

Is the objective lens backward compatible?

Yes, the Seiler Objective Lens offers excellent backward compatibility, ensuring it integrates seamlessly with previous generation equipment.

It is compatible with the following legacy systems:

  • Evolution xR6 Microscope
  • IQ Dental/ENT Microscopes
What clinical procedures is this lens used for?

This interchangeable Seiler Objective Lens is designed for use in various specialized medical and dental fields, allowing users to precisely adjust the working distance on compatible Seiler microscopes and colposcopes. The lens is intended for:

  • Dental Microscopy: Compatible with the Alpha Air, Alpha Slim, Evolution xR6, and IQ dental microscopes.
  • ENT (Ear, Nose, and Throat) Microscopy: Used with compatible Seiler ENT microscopes.
  • Colposcopy: Directly compatible with Seiler Colposcope models 935, 955, and 985.
Is the objective lens housing durable metal?

Yes, the objective lens is built using durable construction suitable for rigorous professional use.

  • The housing is a robust, cylindrical component finished in matte black.
  • Its substantial feel and appearance strongly suggest construction from durable metal materials (such as aluminum) to effectively protect the precision optical components.
  • The exterior features circumferential knurling near the mounting end, designed to facilitate secure gripping and fastening into compatible Seiler microscope and colposcope systems.
Does the lens have a clear focal length label?

Yes, each lens features clear labeling with its focal length, for example, “F-300mm” is engraved on the housing. This makes it easy to identify the specific objective lens during setup.
