About This Original Lens

Vivitek D98-4070 Ultra Long Zoom Lens

The D98-4070 Ultra Long Zoom is a Long Throw lens manufactured by Vivitek as an OEM product. Its optical structure, lens coatings, and body tolerances are matched to the original projector standards, ensuring plug-and-play installation and stable imaging. For installation environments with limited projection distance (e.g., short-distance large images, ultra-short throw against a wall), choosing the correct throw ratio is more critical than opting for a generic lens.

This lens has a throw ratio of 4.00-7.00:1. Throw ratio = projection distance ÷ image width: a smaller value produces a larger image (ideal for short distances in small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on your installation distance and screen size, then match it to this model.

FAQ

Q: How do I choose between an original lens and an alternative lens?

A: Original lenses are manufactured by Vivitek with optical parameters and body tolerances calibrated to the original projector, making them ideal for projects with strict OEM consistency requirements; Zorsika alternative lenses are independently designed and manufactured to the same specifications, with throw ratio, image circle, and mount matched to the original, offering advantages in budget and lead time. Zorsika can supply both options—choose based on your project requirements.

Q: How do I confirm this lens works with my projector?

A: Verify based on the projector's lens mount and panel/chip size; this article lists verified compatible models. Projectors from the same generation and brand often share mounts—if unsure, photograph the nameplate and send it to Zorsika technical support for confirmation.

Q: How do I choose the throw ratio?

A: Throw ratio = projection distance ÷ image width. A smaller value produces a larger image (short-throw/ultra-short-throw suits close-range small spaces), while a larger value requires a greater installation distance. Calculate the required throw ratio range based on installation distance and screen size, then match it to this model's focal range.

Q: How can I ensure the D98-4070 Ultra Long Zoom is genuine?

A: Zorsika supplies genuine products through OEM channels, with original packaging and traceable serial numbers; channel documentation can be provided for bulk projects to ensure they are not refurbished or used parts.

Q: What should I pay attention to when replacing the lens?

A: Always power off the projector and wait for the cooling fan to stop before removal/installation; hold the lens barrel without touching the glass, use an air blower for dust; after installation, test focus before tightening the locking screws, and clean the mount and contacts as you go.

Q: What is the warranty period for the lens?

A: Zorsika provides a 12-month warranty on all projector lenses; for normal use and non-man-made damage (e.g., impact, water ingress, unauthorized disassembly), contact after-sales service directly; the warranty period is based on the shipping document date.
