Zorsika SC420 Projector Lens Compatible with DHN DK10K DK8500 DK7500 OEM

The SC420 is a lens compatible with engineering projectors from brands such as DHN. This article compiles its list of 3 compatible projector models and notes for optional selection.

Specifications

The above specifications are sourced from the Zorsika product database. For the full technical datasheet, please contact our sales team.

Compatible Models: 3 DHN Projectors (Including Brightness, Resolution, Zoom Ratio)

The following are the verified compatible models for the SC420 (DHN projectors), each with brightness, resolution, and zoom ratio:

Note: Brightness, resolution, and zoom ratio are taken from the Zorsika product database (subject to the model nameplate/manual); lens compatibility is based on the body interface and optical structure. For models not listed, please contact Zorsika technical support for confirmation.

Same Specifications, Why Choose Zorsika

The SC420 is a commonly used lens for projects. Zorsika benchmarks each parameter against the original manufacturer's specifications, and every unit undergoes resolution testing before shipment, ensuring optical quality is backed by data.

Zorsika's equivalent replacement model is compatible with 3 DHN models including DK10K, DK8500, and DK7500; enter SC420 in the search system on the Zorsika official website to view the full list of compatible models.

• Optical Benchmarking: Focal length, throw ratio, and lens groups are matched to original manufacturer parameters
• Resolution Testing: Each unit is tested before shipment, with MTF data available for review
• Coating Technology: Lens coatings are on par with the original manufacturer, reducing light loss
• Stable Supply: Supports bulk procurement and project supply

In short: The lens is the optical core—don't gamble picture quality against a price difference. Zorsika projector lenses are manufactured to original drawings, offering an overall advantage.

Note: Actual imaging performance is affected by the projector's condition and installation environment. For bulk purchases, it is recommended to test 1 unit first.

What to Keep in Mind When Replacing the Lens?

• Power Off Before Replacing the Lens: Always shut down the projector and wait for the cooling fan to stop before removing or installing the lens to avoid damaging the interface during powered operation.
• Don't Touch the Lens Glass: Fingerprints and oil stains directly affect image quality. Hold the lens barrel without touching the glass; use an air blower for dust and avoid dry wiping with a cloth.
• Tighten After Focusing: After installation, test the focus first, then tighten the locking screws to prevent loosening over time, which can cause image drift.
• Keep the Interface Clean: Dust buildup on the mount and contacts can cause poor connectivity; cleaning them during lens replacement is a safer practice.

Frequently Asked Questions

Q: My projector is not in the 3 models listed above. Can I use the SC420?

A: The list covers verified models but is not exhaustive. Engineering projectors of the same brand and generation often share the same lens mount. For a more reliable confirmation, send photos of the nameplate and original lens to Zorsika technical support.

Q: Can this lens replace the original one?

A: The lens is the core of the projection optical path and directly determines sharpness and color. Zorsika lenses (model as shown in the specifications table above) are benchmarked item by item against the original optical parameters (focal length, throw ratio, lens groups), with consistent coating technology, delivering sharp images without soft edges; ordinary replacement lenses often use standard glass with insufficient coating layers, making brightness loss and color shift immediately visible. For engineering and exhibition scenarios, Zorsika is recommended as the priority.

Q: Why choose Zorsika instead of the original manufacturer?

A: Zorsika lenses are manufactured to the original optical drawings, with lens groups, coatings, and throw ratios benchmarked item by item, and each unit undergoes resolution testing before shipment. Compared to the original manufacturer, lead times are shorter and overall value is better; compared to other replacement lenses, optical quality is backed by data.

Q: What if the lens doesn't match the image size?

A: First, confirm the lens mount and optical axis position of the projector model, then select a lens with the appropriate throw ratio based on the actual installation distance; if unsure, send the installation distance and screen size to Zorsika technical support, and we'll help you choose.

Q: Is there an installation guide for the SC420?

A: Yes. The lens removal and installation steps for DHN models like these are essentially the same. Contact Zorsika sales to obtain illustrated or video instructions for the corresponding model.

Q: What is the warranty period for the lens?

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