IPL Filter Wavelengths: Reading the 430-1200nm Wide Spectrum Against the Function List

IPL machines are often described by a single wavelength range, but the published specification section on this site is more specific: five filter wavelengths, a wide-spectrum principle, and a ten-item function list. This article reads those three pieces together and shows where each piece ends.

The five filter wavelengths

The specification section lists filter wavelengths of 430nm, 480nm, 530nm, 590nm and 640nm. These are the filters in the published table. A filter is a physical component that selects part of the emitted light; the list of five filters is the concrete, checkable part of the specification. Before ordering, confirm which filters are included in the configuration you plan to buy, whether any filter is optional, and whether additional filters are available. Do not assume that every filter in the table is included in every quoted price.

The wide-spectrum principle and the 950-1200nm band

The company describes a wide-spectrum principle of 430nm–1200nm high-energy broad-spectrum light. It also describes the 950–1200nm filter band as ineffective for treatment and able to absorb water. Both statements are company descriptions, not table values. The distinction matters: the five filter wavelengths are table entries, while the 430–1200nm range and the 950–1200nm band description are principle explanations. A buyer should ask the supplier to explain, in practical terms, what the wide-spectrum principle means for the functions in the list below, and which filter is used for each function.

The ten-item function list

The published function list reads: pigment removal, dark circles, skin tightening, pore remover, blood vessels removal, hair removal, acne treatment, wrinkle remover, skin rejuvenation, and pigmentation correctors. Ten functions is a long list, and a buyer should not assume that every function is equally supported by every filter. Ask the supplier to map each function you care about to a filter and a setting, and to state which functions are included in the standard configuration. Functions without a stated filter and setting are intentions, not specifications.

The rest of the specification section

The remaining table entries are a drive power of 2000W, a spot size of 15*50mm as standard, a frequency of 1–10 Hz adjustable, a pulse duration of 10–400ms, an energy range of 1–50J/cm2, continuous standby working for 18 hours, continuous crystal contact cooling from -4℃ to 2℃, a display of 10.4 inch TFT color touch LCD, and a specification entry of 12000UF as published. The 12000UF entry is quoted exactly as published, without a meaning added. The 18-hour standby figure describes standby working, not continuous treatment, and should not be read as a treatment-time figure.

Questions to ask before ordering

• Which filters are included in the quoted configuration, and which are optional?
• Which filter and setting correspond to each function you plan to use?
• What does the 950–1200nm band description mean in practice for your functions?
• What is the energy range per filter, if it differs by filter?
• Which certification documents apply to your model and market?
• What are the price, configuration, lead time, packaging and warranty terms for your order?

Certificates available upon request. Before ordering, confirm price, configuration, lead time and warranty on inquiry.

Mapping functions to filters: a worked approach

Take the ten-item function list and ask the supplier to map each function you plan to use to a filter and a setting. For example, if hair removal and pigment removal are both on your list, ask which filter is used for each, whether the energy range differs by filter, and whether the spot size changes by filter. Write the mapping down as a table: function, filter, energy range, spot size, and cooling setting. Any function that cannot be mapped to a filter and a setting stays on the intentions list, not the specifications list. This mapping exercise often reveals that a long function list rests on a small number of filters, which is useful information, not a criticism: it tells the buyer what the machine actually does with its five filters.

Filter replacement and total cost

Filters are consumable components in intense pulsed light systems. Ask the supplier for the expected filter life, the replacement price, whether the operator can replace filters, and whether filter changes require recalibration. Also ask whether the quoted price includes a full filter set or a subset, and what additional filters cost. A system with a low purchase price and expensive, short-lived filters can cost more over its working life than a system with a higher purchase price and durable filters. Total cost questions belong in the first inquiry, not after delivery.

Questions that only the supplier can answer

Several IPL questions need supplier answers. The energy range per filter, if it differs by filter, is not stated in the table, which gives a single range of 1–50J/cm2. Whether that range applies to every filter or varies by filter changes how the machine is used, and only the supplier can say. The meaning of the 12000UF specification entry is another supplier question: it is quoted exactly as published, without a meaning added, and a buyer should ask what it measures before relying on it. Filter replacement intervals, replacement prices, and whether replacement needs recalibration are also supplier questions, and they affect total cost more than the filter list itself.

Operating knowledge is supplier-only as well. The table does not describe a treatment protocol: which filter and setting for which function, how settings change across a session, or what interval guidance applies. Those belong in training. A buyer who orders on the filter list alone, without the mapping from functions to filters and settings, has bought a set of components without knowing how they are meant to be combined. The mapping exercise described earlier in this article is the way to close that gap, and it should be completed before ordering, not after delivery.

Commercial terms complete the inquiry. Warranty scope, service method, consumable prices, and response times are not in the table. The 18-hour standby figure is sometimes misread as a treatment capacity figure; it describes standby working, and the buyer should ask separately about continuous treatment duration and cooling recovery. A complete IPL inquiry therefore has three parts: the filter and setting mapping, the consumable and total cost picture, and the commercial terms. All three parts should be recorded in writing.

A note on sources used in this article

Every figure in this article comes from one of two places: a published specification section on this site, or a company description that is marked as such. No figure comes from a third-party listing, a review, or a general knowledge claim about how such machines usually perform. Where a published entry is truncated, this article says so and does not complete it. Where a figure is a company statement, the article marks it as a company statement rather than presenting it as a verified fact. That discipline is what makes the article usable as a buying tool: a buyer can trace every figure back to its source section and can see, at a glance, which figures are table values and which are descriptions. Before relying on any figure in a purchase decision, confirm it with the supplier for the exact model and configuration you plan to buy, and have the confirmation recorded in writing. A figure confirmed in writing for your configuration is evidence; a figure read on a website, without that confirmation, is a starting point for an inquiry.
